WebMD5 produces a 128-bit (16 byte) message digest, which makes it faster than SHA1 or SHA2. This is the least secure algorithm. HMAC-SHA1 (Hash Message Authentication Code — Secure Hash Algorithm 1) SHA1 produces a 160-bit (20 byte) message digest. Although slower than MD5, this larger digest size makes it stronger against brute force … WebCreate a message digest. Hashing algorithms are used to create a message digest to ensure that data integrity is maintained. A sender creates a message digest by performing the hash function on the data files that are transmitted. The receiver performs the same action on the data received and compares the two message digests.
