◆ PSA_RAW_KEY_AGREEMENT_OUTPUT_MAX_SIZE
| #define PSA_RAW_KEY_AGREEMENT_OUTPUT_MAX_SIZE /* implementation-defined value */ |
Sufficient output buffer size for psa_raw_key_agreement(), for any of the supported key types and key agreement algorithms.
If the size of the output buffer is at least this large, it is guaranteed that psa_raw_key_agreement() will not fail due to an insufficient buffer size.
See also PSA_RAW_KEY_AGREEMENT_OUTPUT_SIZE().
◆ PSA_RAW_KEY_AGREEMENT_OUTPUT_SIZE
| #define PSA_RAW_KEY_AGREEMENT_OUTPUT_SIZE | ( | key_type, | |
| key_bits | |||
| ) | /* implementation-defined value */ |
Sufficient output buffer size for psa_raw_key_agreement().
If the size of the output buffer is at least this large, it is guaranteed that psa_raw_key_agreement() 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_RAW_KEY_AGREEMENT_OUTPUT_MAX_SIZE.
- Parameters
-
key_type A supported key type. key_bits The size of the key in bits.
- Returns
- A sufficient output buffer size for the specified key type and size. 0 if key type is not supported. If the parameters are not valid, the return value is unspecified.
