191 ASN1_STRING_print_ex, ASN1_STRING_print_ex_fp \- ASN1_STRING output routines.
195 \& #include <openssl/asn1.h>
198 \& int ASN1_STRING_print_ex(BIO *out, ASN1_STRING *str, unsigned long flags);
199 \& int ASN1_STRING_print_ex_fp(FILE *fp, ASN1_STRING *str, unsigned long flags);
200 \& int ASN1_STRING_print(BIO *out, ASN1_STRING *str);
203 These functions output an \fBASN1_STRING\fR structure. \fBASN1_STRING\fR is used to
204 represent all the ASN1 string types.
206 \fIASN1_STRING_print_ex()\fR outputs \fBstr\fR to \fBout\fR, the format is determined by
207 the options \fBflags\fR. \fIASN1_STRING_print_ex_fp()\fR is identical except it outputs
210 \fIASN1_STRING_print()\fR prints \fBstr\fR to \fBout\fR but using a different format to
211 \fIASN1_STRING_print_ex()\fR. It replaces unprintable characters (other than CR, LF)
214 \fIASN1_STRING_print()\fR is a legacy function which should be avoided in new applications.
216 Although there are a large number of options frequently \fBASN1_STRFLAGS_RFC2253\fR is
217 suitable, or on UTF8 terminals \fBASN1_STRFLAGS_RFC2253 & ~ASN1_STRFLAGS_ESC_MSB\fR.
219 The complete set of supported options for \fBflags\fR is listed below.
221 Various characters can be escaped. If \fBASN1_STRFLGS_ESC_2253\fR is set the characters
222 determined by RFC2253 are escaped. If \fBASN1_STRFLGS_ESC_CTRL\fR is set control
223 characters are escaped. If \fBASN1_STRFLGS_ESC_MSB\fR is set characters with the
224 MSB set are escaped: this option should \fBnot\fR be used if the terminal correctly
225 interprets UTF8 sequences.
227 Escaping takes several forms.
229 If the character being escaped is a 16 bit character then the form \*(L"\eWXXXX\*(R" is used
230 using exactly four characters for the hex representation. If it is 32 bits then
231 \*(L"\eUXXXXXXXX\*(R" is used using eight characters of its hex representation. These forms
232 will only be used if UTF8 conversion is not set (see below).
234 Printable characters are normally escaped using the backslash \*(L'\e\*(R' character. If
235 \fBASN1_STRFLGS_ESC_QUOTE\fR is set then the whole string is instead surrounded by
236 double quote characters: this is arguably more readable than the backslash
237 notation. Other characters use the \*(L"\eXX\*(R" using exactly two characters of the hex
240 If \fBASN1_STRFLGS_UTF8_CONVERT\fR is set then characters are converted to UTF8
241 format first. If the terminal supports the display of UTF8 sequences then this
242 option will correctly display multi byte characters.
244 If \fBASN1_STRFLGS_IGNORE_TYPE\fR is set then the string type is not interpreted at
245 all: everything is assumed to be one byte per character. This is primarily for
246 debugging purposes and can result in confusing output in multi character strings.
248 If \fBASN1_STRFLGS_SHOW_TYPE\fR is set then the string type itself is printed out
249 before its value (for example \*(L"BMPSTRING"), this actually uses \fIASN1_tag2str()\fR.
251 The content of a string instead of being interpreted can be \*(L"dumped": this just
252 outputs the value of the string using the form #XXXX using hex format for each
255 If \fBASN1_STRFLGS_DUMP_ALL\fR is set then any type is dumped.
257 Normally non character string types (such as OCTET STRING) are assumed to be
258 one byte per character, if \fBASN1_STRFLAGS_DUMP_UNKNOWN\fR is set then they will
261 When a type is dumped normally just the content octets are printed, if
262 \fBASN1_STRFLGS_DUMP_DER\fR is set then the complete encoding is dumped
263 instead (including tag and length octets).
265 \fBASN1_STRFLGS_RFC2253\fR includes all the flags required by RFC2253. It is
