◆ MBEDTLS_PSA_ALG_AEAD_EQUAL

#define MBEDTLS_PSA_ALG_AEAD_EQUAL ( aead_alg_1,
aead_alg_2
)
Value:
(!(((aead_alg_1) ^ (aead_alg_2)) & \
~(PSA_ALG_AEAD_TAG_LENGTH_MASK | PSA_ALG_AEAD_AT_LEAST_THIS_LENGTH_FLAG)))

Check if two AEAD algorithm identifiers refer to the same AEAD algorithm regardless of the tag length they encode.

Parameters
aead_alg_1 An AEAD algorithm identifier.
aead_alg_2 An AEAD algorithm identifier.
Returns
1 if both identifiers refer to the same AEAD algorithm, 0 otherwise. Unspecified if neither aead_alg_1 nor aead_alg_2 are a supported AEAD algorithm.
