Function Documentation

iesys_crypto_hash_get_digest_size()

TSS2_RC iesys_crypto_hash_get_digest_size	(	TPM2_ALG_ID	hashAlg,
		size_t *	size
	)

Provide the digest size for a given hash algorithm.

This function provides the size of the digest for a given hash algorithm.

Parameters

[in]	hashAlg	The hash algorithm to get the size for.
[out]	size	The side of a digest of the hash algorithm.

Return values

TSS2_RC_SUCCESS	on success.
TSS2_ESYS_RC_BAD_VALUE	if hashAlg is unknown or unsupported.
