RIPEMD160(3) FreeBSD Library Functions Manual RIPEMD160(3) NAME RIPEMD160, RIPEMD160_Init, RIPEMD160_Update, RIPEMD160_Final - RIPEMD-160 hash function SYNOPSIS #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); DESCRIPTION RIPEMD-160 is a cryptographic hash function with a 160-bit output. RIPEMD160() computes the RIPEMD-160 message digest of the n bytes at d and places it in md, which must have space for RIPEMD160_DIGEST_LENGTH == 20 bytes of output. The following functions may be used if the message is not completely stored in memory: RIPEMD160_Init() initializes a RIPEMD160_CTX structure. RIPEMD160_Update() can be called repeatedly with chunks of the message to be hashed (len bytes at data). RIPEMD160_Final() places the message digest in md, which must have space for RIPEMD160_DIGEST_LENGTH == 20 bytes of output, and erases the RIPEMD160_CTX. Applications should use the higher level functions EVP_DigestInit(3) etc. instead of calling the hash functions directly. RETURN VALUES RIPEMD160() returns a pointer to the hash value. RIPEMD160_Init(), RIPEMD160_Update(), and RIPEMD160_Final() return 1 for success or 0 otherwise.

CAVEATS Other implementations allow md in RIPEMD160() to be NULL and return a static array, which is not thread safe. FreeBSD 14.1-RELEASE-p8 May 26, 2024 FreeBSD 14.1-RELEASE-p8
