Summary

Declaration

from psa_crypto_pake.h:74

psa_status_t mbedtls_psa_pake_output(mbedtls_psa_pake_operation_t *operation, psa_crypto_driver_pake_step_t step, uint8_t *output, size_t output_size, size_t *output_length);

Arguments

Argument

Declared as

Description

operation

mbedtls_psa_pake_operation_t *

Active PAKE operation.

step

psa_crypto_driver_pake_step_t

The step of the algorithm for which the output is requested.

output

uint8_t *

Buffer where the output is to be written in the format appropriate for this driver \p step. Refer to the documentation of psa_crypto_driver_pake_step_t for more information.

output_size

size_t

Size of the \p output buffer in bytes. This must be at least #PSA_PAKE_OUTPUT_SIZE(\p alg, \p primitive, \p step) where \p alg and \p primitive are the PAKE algorithm and primitive in the operation's cipher suite, and \p step is the output step.

output_length

size_t *

On success, the number of bytes of the returned output.

Return value

#PSA_SUCCESS Success. #PSA_ERROR_BUFFER_TOO_SMALL The size of the \p output buffer is too small. #PSA_ERROR_INSUFFICIENT_ENTROPY \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_output entry point. This function behaves as a pake_output entry point as defined in the PSA driver interface specification for transparent drivers.
