1=pod 2 3=head1 NAME 4 5RIPEMD160, RIPEMD160_Init, RIPEMD160_Update, RIPEMD160_Final - 6RIPEMD-160 hash function 7 8=head1 SYNOPSIS 9 10 #include <openssl/ripemd.h> 11 12 unsigned char *RIPEMD160(const unsigned char *d, unsigned long n, 13 unsigned char *md); 14 15 int RIPEMD160_Init(RIPEMD160_CTX *c); 16 int RIPEMD160_Update(RIPEMD160_CTX *c, const void *data, unsigned long len); 17 int RIPEMD160_Final(unsigned char *md, RIPEMD160_CTX *c); 18 19=head1 DESCRIPTION 20 21RIPEMD-160 is a cryptographic hash function with a 22160 bit output. 23 24RIPEMD160() computes the RIPEMD-160 message digest of the B<n> 25bytes at B<d> and places it in B<md> (which must have space for 26RIPEMD160_DIGEST_LENGTH == 20 bytes of output). If B<md> is NULL, the digest 27is placed in a static array. 28 29The following functions may be used if the message is not completely 30stored in memory: 31 32RIPEMD160_Init() initializes a B<RIPEMD160_CTX> structure. 33 34RIPEMD160_Update() can be called repeatedly with chunks of the message to 35be hashed (B<len> bytes at B<data>). 36 37RIPEMD160_Final() places the message digest in B<md>, which must have 38space for RIPEMD160_DIGEST_LENGTH == 20 bytes of output, and erases 39the B<RIPEMD160_CTX>. 40 41=head1 RETURN VALUES 42 43RIPEMD160() returns a pointer to the hash value. 44 45RIPEMD160_Init(), RIPEMD160_Update() and RIPEMD160_Final() return 1 for 46success, 0 otherwise. 47 48=head1 NOTE 49 50Applications should use the higher level functions 51L<EVP_DigestInit(3)> etc. instead of calling these 52functions directly. 53 54=head1 CONFORMING TO 55 56ISO/IEC 10118-3:2016 Dedicated Hash-Function 1 (RIPEMD-160). 57 58=head1 SEE ALSO 59 60L<EVP_DigestInit(3)> 61 62=head1 COPYRIGHT 63 64Copyright 2000-2019 The OpenSSL Project Authors.
