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 12The following functions have been deprecated since OpenSSL 3.0, and can be 13hidden entirely by defining B<OPENSSL_API_COMPAT> with a suitable version value, 14see L<openssl_user_macros(7)>: 15 16 unsigned char *RIPEMD160(const unsigned char *d, unsigned long n, 17 unsigned char *md); 18 19 int RIPEMD160_Init(RIPEMD160_CTX *c); 20 int RIPEMD160_Update(RIPEMD160_CTX *c, const void *data, unsigned long len); 21 int RIPEMD160_Final(unsigned char *md, RIPEMD160_CTX *c); 22 23=head1 DESCRIPTION 24 25All of the functions described on this page are deprecated. 26Applications should instead use L<EVP_DigestInit_ex(3)>, L<EVP_DigestUpdate(3)> 27and L<EVP_DigestFinal_ex(3)>. 28 29RIPEMD-160 is a cryptographic hash function with a 30160 bit output. 31 32RIPEMD160() computes the RIPEMD-160 message digest of the B<n> 33bytes at B<d> and places it in B<md> (which must have space for 34RIPEMD160_DIGEST_LENGTH == 20 bytes of output). If B<md> is NULL, the digest 35is placed in a static array. 36 37The following functions may be used if the message is not completely 38stored in memory: 39 40RIPEMD160_Init() initializes a B<RIPEMD160_CTX> structure. 41 42RIPEMD160_Update() can be called repeatedly with chunks of the message to 43be hashed (B<len> bytes at B<data>). 44 45RIPEMD160_Final() places the message digest in B<md>, which must have 46space for RIPEMD160_DIGEST_LENGTH == 20 bytes of output, and erases 47the B<RIPEMD160_CTX>. 48 49=head1 RETURN VALUES 50 51RIPEMD160() returns a pointer to the hash value. 52 53RIPEMD160_Init(), RIPEMD160_Update() and RIPEMD160_Final() return 1 for 54success, 0 otherwise. 55 56=head1 NOTE 57 58Applications should use the higher level functions 59L<EVP_DigestInit(3)> etc. instead of calling these 60functions directly. 61 62=head1 CONFORMING TO 63 64ISO/IEC 10118-3:2016 Dedicated Hash-Function 1 (RIPEMD-160). 65 66=head1 SEE ALSO 67 68L<EVP_DigestInit(3)> 69 70=head1 HISTORY 71 72All of these functions were deprecated in OpenSSL 3.0. 73 74=head1 COPYRIGHT 75 76Copyright 2000-2020 The OpenSSL Project Authors.
