Summary

Declaration

from crypto_extra.h:1668

#define PSA_PAKE_INPUT_SIZE(alg, primitive, input_step) \ (alg == PSA_ALG_JPAKE && \ primitive == PSA_PAKE_PRIMITIVE(PSA_PAKE_PRIMITIVE_TYPE_ECC, \ PSA_ECC_FAMILY_SECP_R1, 256) ? \ ( \ input_step == PSA_PAKE_STEP_KEY_SHARE ? 65 : \ input_step == PSA_PAKE_STEP_ZK_PUBLIC ? 65 : \ 32 \ ) : \ 0)

Arguments

Argument

Description

alg

A PAKE algorithm (\c PSA_ALG_XXX value such that #PSA_ALG_IS_PAKE(\p alg) is true).

primitive

A primitive of type ::psa_pake_primitive_t that is compatible with algorithm \p alg.

input_step

A value of type ::psa_pake_step_t that is valid for the algorithm \p alg.

Return value

A sufficient input buffer size for the specified input, cipher suite and algorithm. If the cipher suite, the input type or PAKE algorithm is not recognized, or the parameters are incompatible, return 0.
