mbedtls_ecp_group_id	mbedtls_ecc_group_of_psa (psa_ecc_family_t curve, size_t bits, int bits_is_sloppy)

Detailed Description

Function Documentation

mbedtls_ecp_group_id mbedtls_ecc_group_of_psa	(	psa_ecc_family_t	curve,
		size_t	bits,
		int	bits_is_sloppy
	)

Convert an ECC curve identifier from the PSA encoding to Mbed TLS.

Note: This function is provided solely for the convenience of Mbed TLS and may be removed at any time without notice.

Parameters

curve	A PSA elliptic curve identifier (`PSA_ECC_FAMILY_xxx`).
bits	The bit-length of a private key on `curve`.
bits_is_sloppy	If true, `bits` may be the bit-length rounded up to the nearest multiple of 8. This allows the caller to infer the exact curve from the length of a key which is supplied as a byte string.

Returns: The corresponding Mbed TLS elliptic curve identifier (MBEDTLS_ECP_DP_xxx).; MBEDTLS_ECP_DP_NONE if curve is not recognized.; MBEDTLS_ECP_DP_NONE if bits is not correct for curve.

	)

inlinestatic

Convert an ECC curve identifier from the Mbed TLS encoding to PSA.

Note: This function is provided solely for the convenience of Mbed TLS and may be removed at any time without notice.

Parameters

	grpid	An Mbed TLS elliptic curve identifier (`MBEDTLS_ECP_DP_xxx`).
[out]	bits	On success, the bit size of the curve.

Returns: The corresponding PSA elliptic curve identifier (PSA_ECC_FAMILY_xxx).; 0 on failure (grpid is not recognized).
