◆ PSA_ASYMMETRIC_DECRYPT_OUTPUT_MAX_SIZE
| #define PSA_ASYMMETRIC_DECRYPT_OUTPUT_MAX_SIZE /* implementation-defined value */ |
A sufficient output buffer size for psa_asymmetric_decrypt(), for any of the supported key types and asymmetric encryption algorithms.
If the size of the output buffer is at least this large, it is guaranteed that psa_asymmetric_decrypt() will not fail due to an insufficient buffer size.
See also PSA_ASYMMETRIC_DECRYPT_OUTPUT_SIZE().
◆ PSA_ASYMMETRIC_DECRYPT_OUTPUT_SIZE
| #define PSA_ASYMMETRIC_DECRYPT_OUTPUT_SIZE | ( | key_type, | |
| key_bits, | |||
| alg ) |
Sufficient output buffer size for psa_asymmetric_decrypt().
If the size of the output buffer is at least this large, it is guaranteed that psa_asymmetric_decrypt() will not fail due to an insufficient buffer size. The actual size of the output might be smaller in any given call.
See also PSA_ASYMMETRIC_DECRYPT_OUTPUT_MAX_SIZE.
- Parameters
-
key_type An asymmetric key type, either a key pair or a public key. key_bits The size of the key in bits. alg An asymmetric encryption algorithm: a value of type psa_algorithm_t such that PSA_ALG_IS_ASYMMETRIC_ENCRYPTION( alg) is true.
- Returns
- A sufficient output buffer size for the specified asymmetric encryption algorithm and key parameters. 0 if the asymmetric encryption algorithm and key parameters are not supported. Unspecified if the parameters are not valid.
◆ PSA_ASYMMETRIC_ENCRYPT_OUTPUT_MAX_SIZE
| #define PSA_ASYMMETRIC_ENCRYPT_OUTPUT_MAX_SIZE /* implementation-defined value */ |
A sufficient output buffer size for psa_asymmetric_encrypt(), for any of the supported key types and asymmetric encryption algorithms.
If the size of the output buffer is at least this large, it is guaranteed that psa_asymmetric_encrypt() will not fail due to an insufficient buffer size.
See also PSA_ASYMMETRIC_ENCRYPT_OUTPUT_SIZE().
◆ PSA_ASYMMETRIC_ENCRYPT_OUTPUT_SIZE
| #define PSA_ASYMMETRIC_ENCRYPT_OUTPUT_SIZE | ( | key_type, | |
| key_bits, | |||
