Arguments

Argument

Declared as

Description

operation

mbedtls_psa_pake_operation_t *

Active PAKE operation.

output

uint8_t *

Output buffer for implicit key.

output_size

size_t

Size of the output buffer in bytes.

output_length

size_t *

On success, the number of bytes of the implicit key.

Return value

#PSA_SUCCESS Success. #PSA_ERROR_NOT_SUPPORTED Input from a PAKE is not supported by the algorithm in the \p output key derivation operation. #PSA_ERROR_INSUFFICIENT_MEMORY \emptydescription #PSA_ERROR_CORRUPTION_DETECTED \emptydescription #PSA_ERROR_DATA_CORRUPT \emptydescription #PSA_ERROR_DATA_INVALID \emptydescription

Notes

The signature of this function is that of a PSA driver pake_get_implicit_key entry point. This function behaves as a pake_get_implicit_key entry point as defined in the PSA driver interface specification for transparent drivers.
