gEfiSecurityPkgTokenSpaceGuid.PcdTpm2HashMask

This PCD indicates Hash mask for TPM 2.0. Bit definition strictly follows TCG Algorithm Registry.


If this bit is set, that means this algorithm is needed to extend to PCR.

If this bit is clear, that means this algorithm is NOT needed to extend to PCR.

If all the bits are clear, that means hash algorithm is determined by current Active PCR Banks.

BIT0 - SHA1.

BIT1 - SHA256.

BIT2 - SHA384.

BIT3 - SHA512.

BIT4 - SM3_256.
