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). If md is NULL, the digest is placed in a static

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

Applications should use the higher level functions EVP_DigestInit(3)
etc. instead of calling the hash functions directly.


RIPEMD160() returns a pointer to the hash value.
RIPEMD160_Init(), RIPEMD160_Update() and RIPEMD160_Final() do not
return values.
