An implementation of the SHA-1 hash algorithm in C.
int SHA1Init(SHA1Context* Ctx);
Call this before calling other function to init Ctx
.
int SHA1Update(SHA1Context* Ctx, const BYTE buf[], unsigned int length);
This function accepts an array of octets buf
as the next portion of the message. length
is the length of buf
.
int SHA1Result(SHA1Context* Ctx, BYTE digest[20]);
Computes the message digest and stores to digest
.
