+.SH DESCRIPTION
+.IX Header "DESCRIPTION"
+All of the functions described on this page are deprecated.
+Applications should instead use \fBEVP_DigestInit_ex\fR\|(3), \fBEVP_DigestUpdate\fR\|(3)
+and \fBEVP_DigestFinal_ex\fR\|(3).
+.PP
+RIPEMD\-160 is a cryptographic hash function with a
+160 bit output.
+.PP
+\&\fBRIPEMD160()\fR computes the RIPEMD\-160 message digest of the \fBn\fR
+bytes at \fBd\fR and places it in \fBmd\fR (which must have space for
+RIPEMD160_DIGEST_LENGTH == 20 bytes of output). If \fBmd\fR is NULL, the digest
+is placed in a static array.
+.PP
+The following functions may be used if the message is not completely
+stored in memory:
+.PP
+\&\fBRIPEMD160_Init()\fR initializes a \fBRIPEMD160_CTX\fR structure.
+.PP
+\&\fBRIPEMD160_Update()\fR can be called repeatedly with chunks of the message to
+be hashed (\fBlen\fR bytes at \fBdata\fR).
+.PP
+\&\fBRIPEMD160_Final()\fR places the message digest in \fBmd\fR, which must have
+space for RIPEMD160_DIGEST_LENGTH == 20 bytes of output, and erases
+the \fBRIPEMD160_CTX\fR.
+.SH "RETURN VALUES"
+.IX Header "RETURN VALUES"
+\&\fBRIPEMD160()\fR returns a pointer to the hash value.
+.PP
+\&\fBRIPEMD160_Init()\fR, \fBRIPEMD160_Update()\fR and \fBRIPEMD160_Final()\fR return 1 for
+success, 0 otherwise.
+.SH NOTE
+.IX Header "NOTE"
+Applications should use the higher level functions
+\&\fBEVP_DigestInit\fR\|(3) etc. instead of calling these
+functions directly.
