WOLFSSL_API void wc_InitMd2(Md2 *)
This function initializes md2. This is automatically called by wc_Md2Hash.
Definition: md2.c:43
WOLFSSL_API void wc_Md2Update(Md2 *, const byte *, word32)
Can be called to continually hash the provided byte array of length len.
Definition: md2.c:52
WOLFSSL_API void wc_Md2Final(Md2 *, byte *)
Finalizes hashing of data. Result is placed into hash.
Definition: md2.c:117
WOLFSSL_API int wc_Md2Hash(const byte *, word32, byte *)
Convenience function, handles all the hashing and places the result into hash.
