| 203 | .SH "DESCRIPTION" |
| 204 | The \fBverify\fR command verifies certificate chains. |
| 205 | .SH "COMMAND OPTIONS" |
| 206 | .Ip "\fB\-CApath directory\fR" 4 |
| 207 | A directory of trusted certificates. The certificates should have names |
| 208 | of the form: hash.0 or have symbolic links to them of this |
| 209 | form ("hash\*(R" is the hashed certificate subject name: see the \fB\-hash\fR option |
| 210 | of the \fBx509\fR utility). Under Unix the \fBc_rehash\fR script will automatically |
| 211 | create symbolic links to a directory of certificates. |
| 212 | .Ip "\fB\-CAfile file\fR" 4 |
| 213 | A file of trusted certificates. The file should contain multiple certificates |
| 214 | in \s-1PEM\s0 format concatenated together. |
| 215 | .Ip "\fB\-untrusted file\fR" 4 |
| 216 | A file of untrusted certificates. The file should contain multiple certificates |
| 217 | .Ip "\fB\-purpose purpose\fR" 4 |
| 218 | the intended use for the certificate. Without this option no chain verification |
| 219 | will be done. Currently accepted uses are \fBsslclient\fR, \fBsslserver\fR, |
| 220 | \fBnssslserver\fR, \fBsmimesign\fR, \fBsmimeencrypt\fR. See the \fB\s-1VERIFY\s0 \s-1OPERATION\s0\fR |
| 221 | section for more information. |
| 222 | .Ip "\fB\-help\fR" 4 |
| 223 | prints out a usage message. |
| 224 | .Ip "\fB\-verbose\fR" 4 |
| 225 | print extra information about the operations being performed. |
| 226 | .Ip "\fB\-issuer_checks\fR" 4 |
| 227 | print out diagnostics relating to searches for the issuer certificate |
| 228 | of the current certificate. This shows why each candidate issuer |
| 229 | certificate was rejected. However the presence of rejection messages |
| 230 | does not itself imply that anything is wrong: during the normal |
| 231 | verify process several rejections may take place. |
| 232 | .Ip "\fB\-\fR" 4 |
| 233 | marks the last option. All arguments following this are assumed to be |
| 234 | certificate files. This is useful if the first certificate filename begins |
| 235 | with a \fB\-\fR. |
| 236 | .Ip "\fBcertificates\fR" 4 |
| 237 | one or more certificates to verify. If no certificate filenames are included |
| 238 | then an attempt is made to read a certificate from standard input. They should |
| 239 | all be in \s-1PEM\s0 format. |
| 240 | .SH "VERIFY OPERATION" |
| 241 | The \fBverify\fR program uses the same functions as the internal SSL and S/MIME |
| 242 | verification, therefore this description applies to these verify operations |
| 243 | too. |
| 244 | .PP |
| 245 | There is one crucial difference between the verify operations performed |
| 246 | by the \fBverify\fR program: wherever possible an attempt is made to continue |
| 247 | after an error whereas normally the verify operation would halt on the |
| 248 | first error. This allows all the problems with a certificate chain to be |
| 249 | determined. |
| 250 | .PP |
| 251 | The verify operation consists of a number of separate steps. |
| 252 | .PP |
| 253 | Firstly a certificate chain is built up starting from the supplied certificate |
| 254 | and ending in the root CA. It is an error if the whole chain cannot be built |
| 255 | up. The chain is built up by looking up the issuers certificate of the current |
| 256 | certificate. If a certificate is found which is its own issuer it is assumed |
| 257 | to be the root CA. |
| 258 | .PP |
| 259 | The process of \*(L'looking up the issuers certificate\*(R' itself involves a number |
| 260 | of steps. In versions of OpenSSL before 0.9.5a the first certificate whose |
| 261 | subject name matched the issuer of the current certificate was assumed to be |
| 262 | the issuers certificate. In OpenSSL 0.9.6 and later all certificates |
| 263 | whose subject name matches the issuer name of the current certificate are |
| 264 | subject to further tests. The relevant authority key identifier components |
| 265 | of the current certificate (if present) must match the subject key identifier |
| 266 | (if present) and issuer and serial number of the candidate issuer, in addition |
| 267 | the keyUsage extension of the candidate issuer (if present) must permit |
| 268 | certificate signing. |
| 269 | .PP |
| 270 | The lookup first looks in the list of untrusted certificates and if no match |
| 271 | is found the remaining lookups are from the trusted certificates. The root CA |
| 272 | is always looked up in the trusted certificate list: if the certificate to |
| 273 | verify is a root certificate then an exact match must be found in the trusted |
| 274 | list. |
| 275 | .PP |
| 276 | The second operation is to check every untrusted certificate's extensions for |
| 277 | consistency with the supplied purpose. If the \fB\-purpose\fR option is not included |
| 278 | then no checks are done. The supplied or \*(L"leaf\*(R" certificate must have extensions |
| 279 | compatible with the supplied purpose and all other certificates must also be valid |
| 280 | CA certificates. The precise extensions required are described in more detail in |
| 281 | the \fBCERTIFICATE EXTENSIONS\fR section of the \fBx509\fR utility. |
| 282 | .PP |
| 283 | The third operation is to check the trust settings on the root CA. The root |
| 284 | CA should be trusted for the supplied purpose. For compatibility with previous |
| 285 | versions of SSLeay and OpenSSL a certificate with no trust settings is considered |
| 286 | to be valid for all purposes. |
| 287 | .PP |
| 288 | The final operation is to check the validity of the certificate chain. The validity |
| 289 | period is checked against the current system time and the notBefore and notAfter |
| 290 | dates in the certificate. The certificate signatures are also checked at this |
| 291 | point. |
| 292 | .PP |
| 293 | If all operations complete successfully then certificate is considered valid. If |
| 294 | any operation fails then the certificate is not valid. |
| 295 | .SH "DIAGNOSTICS" |
| 296 | When a verify operation fails the output messages can be somewhat cryptic. The |
| 297 | general form of the error message is: |
| 298 | .PP |
| 299 | .Vb 2 |
| 300 | \& server.pem: /C=AU/ST=Queensland/O=CryptSoft Pty Ltd/CN=Test CA (1024 bit) |
| 301 | \& error 24 at 1 depth lookup:invalid CA certificate |
| 302 | .Ve |
| 303 | The first line contains the name of the certificate being verified followed by |
| 304 | the subject name of the certificate. The second line contains the error number |
| 305 | and the depth. The depth is number of the certificate being verified when a |
| 306 | problem was detected starting with zero for the certificate being verified itself |
| 307 | then 1 for the CA that signed the certificate and so on. Finally a text version |
| 308 | of the error number is presented. |
| 309 | .PP |
| 310 | An exhaustive list of the error codes and messages is shown below, this also |
| 311 | includes the name of the error code as defined in the header file x509_vfy.h |
| 312 | Some of the error codes are defined but never returned: these are described |
| 313 | as \*(L"unused\*(R". |
| 314 | .Ip "\fB0 X509_V_OK: ok\fR" 4 |
| 315 | the operation was successful. |
| 316 | .Ip "\fB2 X509_V_ERR_UNABLE_TO_GET_ISSUER_CERT: unable to get issuer certificate\fR" 4 |
| 317 | the issuer certificate could not be found: this occurs if the issuer certificate |
| 318 | of an untrusted certificate cannot be found. |
| 319 | .Ip "\fB3 X509_V_ERR_UNABLE_TO_GET_CRL unable to get certificate \s-1CRL\s0\fR" 4 |
| 320 | the \s-1CRL\s0 of a certificate could not be found. Unused. |
| 321 | .Ip "\fB4 X509_V_ERR_UNABLE_TO_DECRYPT_CERT_SIGNATURE: unable to decrypt certificate's signature\fR" 4 |
| 322 | the certificate signature could not be decrypted. This means that the actual signature value |
| 323 | could not be determined rather than it not matching the expected value, this is only |
| 324 | meaningful for \s-1RSA\s0 keys. |
| 325 | .Ip "\fB5 X509_V_ERR_UNABLE_TO_DECRYPT_CRL_SIGNATURE: unable to decrypt \s-1CRL\s0's signature\fR" 4 |
| 326 | the \s-1CRL\s0 signature could not be decrypted: this means that the actual signature value |
| 327 | could not be determined rather than it not matching the expected value. Unused. |
| 328 | .Ip "\fB6 X509_V_ERR_UNABLE_TO_DECODE_ISSUER_PUBLIC_KEY: unable to decode issuer public key\fR" 4 |
| 329 | the public key in the certificate SubjectPublicKeyInfo could not be read. |
| 330 | .Ip "\fB7 X509_V_ERR_CERT_SIGNATURE_FAILURE: certificate signature failure\fR" 4 |
| 331 | the signature of the certificate is invalid. |
| 332 | .Ip "\fB8 X509_V_ERR_CRL_SIGNATURE_FAILURE: \s-1CRL\s0 signature failure\fR" 4 |
| 333 | the signature of the certificate is invalid. Unused. |
| 334 | .Ip "\fB9 X509_V_ERR_CERT_NOT_YET_VALID: certificate is not yet valid\fR" 4 |
| 335 | the certificate is not yet valid: the notBefore date is after the current time. |
| 336 | .Ip "\fB10 X509_V_ERR_CERT_HAS_EXPIRED: certificate has expired\fR" 4 |
| 337 | the certificate has expired: that is the notAfter date is before the current time. |
| 338 | .Ip "\fB11 X509_V_ERR_CRL_NOT_YET_VALID: \s-1CRL\s0 is not yet valid\fR" 4 |
| 339 | the \s-1CRL\s0 is not yet valid. Unused. |
| 340 | .Ip "\fB12 X509_V_ERR_CRL_HAS_EXPIRED: \s-1CRL\s0 has expired\fR" 4 |
| 341 | the \s-1CRL\s0 has expired. Unused. |
| 342 | .Ip "\fB13 X509_V_ERR_ERROR_IN_CERT_NOT_BEFORE_FIELD: format error in certificate's notBefore field\fR" 4 |
| 343 | the certificate notBefore field contains an invalid time. |
| 344 | .Ip "\fB14 X509_V_ERR_ERROR_IN_CERT_NOT_AFTER_FIELD: format error in certificate's notAfter field\fR" 4 |
| 345 | the certificate notAfter field contains an invalid time. |
| 346 | .Ip "\fB15 X509_V_ERR_ERROR_IN_CRL_LAST_UPDATE_FIELD: format error in \s-1CRL\s0's lastUpdate field\fR" 4 |
| 347 | the \s-1CRL\s0 lastUpdate field contains an invalid time. Unused. |
| 348 | .Ip "\fB16 X509_V_ERR_ERROR_IN_CRL_NEXT_UPDATE_FIELD: format error in \s-1CRL\s0's nextUpdate field\fR" 4 |
| 349 | the \s-1CRL\s0 nextUpdate field contains an invalid time. Unused. |
| 350 | .Ip "\fB17 X509_V_ERR_OUT_OF_MEM: out of memory\fR" 4 |
| 351 | an error occurred trying to allocate memory. This should never happen. |
| 352 | .Ip "\fB18 X509_V_ERR_DEPTH_ZERO_SELF_SIGNED_CERT: self signed certificate\fR" 4 |
| 353 | the passed certificate is self signed and the same certificate cannot be found in the list of |
| 354 | trusted certificates. |
| 355 | .Ip "\fB19 X509_V_ERR_SELF_SIGNED_CERT_IN_CHAIN: self signed certificate in certificate chain\fR" 4 |
| 356 | the certificate chain could be built up using the untrusted certificates but the root could not |
| 357 | be found locally. |
| 358 | .Ip "\fB20 X509_V_ERR_UNABLE_TO_GET_ISSUER_CERT_LOCALLY: unable to get local issuer certificate\fR" 4 |
| 359 | the issuer certificate of a locally looked up certificate could not be found. This normally means |
| 360 | the list of trusted certificates is not complete. |
| 361 | .Ip "\fB21 X509_V_ERR_UNABLE_TO_VERIFY_LEAF_SIGNATURE: unable to verify the first certificate\fR" 4 |
| 362 | no signatures could be verified because the chain contains only one certificate and it is not |
| 363 | self signed. |
| 364 | .Ip "\fB22 X509_V_ERR_CERT_CHAIN_TOO_LONG: certificate chain too long\fR" 4 |

| 367 | the certificate has been revoked. Unused. |
| 368 | .Ip "\fB24 X509_V_ERR_INVALID_CA: invalid \s-1CA\s0 certificate\fR" 4 |
| 369 | a \s-1CA\s0 certificate is invalid. Either it is not a \s-1CA\s0 or its extensions are not consistent |
| 370 | with the supplied purpose. |
| 371 | .Ip "\fB25 X509_V_ERR_PATH_LENGTH_EXCEEDED: path length constraint exceeded\fR" 4 |

| 396 | .SH "BUGS" |
| 397 | Although the issuer checks are a considerably improvement over the old technique they still |
| 398 | suffer from limitations in the underlying X509_LOOKUP API. One consequence of this is that |
| 399 | trusted certificates with matching subject name must either appear in a file (as specified by the |
| 400 | \fB\-CAfile\fR option) or a directory (as specified by \fB\-CApath\fR. If they occur in both then only |
| 401 | the certificates in the file will be recognised. |
| 402 | .PP |
| 403 | Previous versions of OpenSSL assume certificates with matching subject name are identical and |
| 404 | mishandled them. |
