.. Set up some character translations and predefined strings. \*(-- will
give an unbreakable dash, \*(PI will give pi, \*(L" will give a left
double quote, and \*(R" will give a right double quote. \*(C+ will
give a nicer C++. Capital omega is used to do unbreakable dashes and
therefore won't be available. \*(C` and \*(C' expand to `' in nroff,
nothing in troff, for use with C<>.

Escape single quotes in literal strings from groff's Unicode transform.

If the F register is >0, we'll generate index entries on stderr for
titles (.TH), headers (.SH), subsections (.SS), items (.Ip), and index
entries marked with X<> in POD. Of course, you'll have to process the
output yourself in some meaningful fashion.

Avoid warning from groff about undefined register 'F'.

Title "RIPEMD160_INIT 3" For nroff, turn off justification. Always turn off hyphenation; it makes
way too many mistakes in technical documents.
RIPEMD160, RIPEMD160_Init, RIPEMD160_Update, RIPEMD160_Final - RIPEMD-160 hash function Header "SYNOPSIS" .Vb 1 #include <openssl/ripemd.h> \& unsigned char *RIPEMD160(const unsigned char *d, unsigned long n, unsigned char *md); \& int RIPEMD160_Init(RIPEMD160_CTX *c); int RIPEMD160_Update(RIPEMD160_CTX *c, const void *data, unsigned long len); int RIPEMD160_Final(unsigned char *md, RIPEMD160_CTX *c); .Ve Header "DESCRIPTION" \s-1RIPEMD-160\s0 is a cryptographic hash function with a 160 bit output.

\s-1RIPEMD160\s0() computes the \s-1RIPEMD-160\s0 message digest of the n bytes at d and places it in md (which must have space for \s-1RIPEMD160_DIGEST_LENGTH\s0 == 20 bytes of output). If md is \s-1NULL,\s0 the digest is placed in a static array.

The following functions may be used if the message is not completely stored in memory:

\fBRIPEMD160_Init() initializes a \s-1RIPEMD160_CTX\s0 structure.

\fBRIPEMD160_Update() can be called repeatedly with chunks of the message to be hashed (len bytes at data).

\fBRIPEMD160_Final() places the message digest in md, which must have space for \s-1RIPEMD160_DIGEST_LENGTH\s0 == 20 bytes of output, and erases the \s-1RIPEMD160_CTX\s0.

Header "RETURN VALUES" \s-1RIPEMD160\s0() returns a pointer to the hash value.

\fBRIPEMD160_Init(), RIPEMD160_Update() and RIPEMD160_Final() return 1 for success, 0 otherwise.

Header "NOTE" Applications should use the higher level functions \fBEVP_DigestInit\|(3) etc. instead of calling these functions directly. Header "CONFORMING TO" \s-1ISO/IEC 10118-3:2016\s0 Dedicated Hash-Function 1 (\s-1RIPEMD-160\s0).
