Function Documentation

int SHA1Input (  SHA1Context *  context, const guint8 *  message_array, unsigned  length )

SHA1Input. Description: This function accepts an array of octets as the next portion of the message. Parameters: context: [in/out] The SHA context to update message_array: [in] An array of characters representing the next portion of the message. length: [in] The length of the message in message_array Returns: sha Error Code.

int SHA1Reset (  SHA1Context *  context  )

SHA1Reset. Description: This function will initialize the SHA1Context in preparation for computing a new SHA1 message digest. Parameters: context: [in/out] The context to reset. Returns: sha Error Code.

int SHA1Result (  SHA1Context *  context, guint8  Message_Digest[SHA1HashSize] )

SHA1Result. Description: This function will return the 160-bit message digest into the Message_Digest array provided by the caller. NOTE: The first octet of hash is stored in the 0th element, the last octet of hash in the 19th element. Parameters: context: [in/out] The context to use to calculate the SHA-1 hash. Message_Digest: [out] Where the digest is returned. Returns: sha Error Code.
