208.SH "DESCRIPTION"
74dab6c2 209RIPEMD\-160 is a cryptographic hash function with a
984263bc
MD
210160 bit output.
211.PP
74dab6c2 212\fIRIPEMD160()\fR computes the RIPEMD\-160 message digest of the \fBn\fR
984263bc 213bytes at \fBd\fR and places it in \fBmd\fR (which must have space for
74dab6c2 214RIPEMD160_DIGEST_LENGTH == 20 bytes of output). If \fBmd\fR is NULL, the digest
984263bc
MD
215is placed in a static array.
216.PP
217The following functions may be used if the message is not completely
218stored in memory:
219.PP
74dab6c2 220\fIRIPEMD160_Init()\fR initializes a \fBRIPEMD160_CTX\fR structure.
984263bc 221.PP
74dab6c2 222\fIRIPEMD160_Update()\fR can be called repeatedly with chunks of the message to
984263bc
MD
223be hashed (\fBlen\fR bytes at \fBdata\fR).
224.PP
74dab6c2
JR
225\fIRIPEMD160_Final()\fR places the message digest in \fBmd\fR, which must have
226space for RIPEMD160_DIGEST_LENGTH == 20 bytes of output, and erases
227the \fBRIPEMD160_CTX\fR.
984263bc
MD
228.PP
229Applications should use the higher level functions
230EVP_DigestInit(3) etc. instead of calling the
231hash functions directly.
232.SH "RETURN VALUES"
74dab6c2 233\fIRIPEMD160()\fR returns a pointer to the hash value.
984263bc 234.PP
74dab6c2 235\fIRIPEMD160_Init()\fR, \fIRIPEMD160_Update()\fR and \fIRIPEMD160_Final()\fR do not
