NETWORK SECURITY - SHA 512 (AUTHENTICATION ALGORITHM)

SHA 512 (SECURE HASH ALGORITHM)
1) PAD WITH THE BITS 100..... UNTIL LENGTH OF PLAIN TEXT REACHES 128 LESS THAN MULTIPLE OF 1024 BITS
2) APPEND 128 BIT REPRESENTATION OF ORIGINAL PLAIN TEXT MESSAGE SO THAT LENGTH EQUALS TO MULTIPLE OF 1024
3) INITIALIZE 8 BUFFERS OF SIZE 64 BITS EACH TO STORE INTERMEDIATE RESULTS AND FINAL HASH CODE.
4) PROCESS EACH 1024 BIT BLOCK IN 80 ROUNDS.
5) OUTPUT IN BUFFERS IS THE 512 BIT HASH CODE
