Does the CEC1702 support SHA-384?
  • Yes, the CEC1702 supports SHA-384.
  • To support SHA-384 by using the SHA-512 mode, the initial values that are located at the Initial Hash Value address in the memory space must be changed to the correct values for SHA-384. Then the result must be truncated.

Initial Values For SHA-384:
H0 = cbbb9d5dc1059ed8
H1 = 629a292a367cd507
H2 = 9159015a3070dd17
H3 = 152fecd8f70e5939
H4 = 67332667ffc00b31
H5 = 8eb44a8768581511
H6= db0c2e0d64f98fa7
H7 = 47b5481dbefa4fa4

Initial Values For SHA-512:
H0 = 6a09e667f3bcc908
