mbedtls_ecp_group_id mbedtls_ecc_group_from_psa | ( | psa_ecc_family_t | family, |
size_t | bits ) |
Convert an ECC curve identifier from the PSA encoding to Mbed TLS.
family | A PSA elliptic curve family identifier (PSA_ECC_FAMILY_xxx ). |
bits | The bit-length of a private key on curve . |
MBEDTLS_ECP_DP_xxx
). curve
and bits
is not supported. psa_ecc_family_t mbedtls_ecc_group_to_psa | ( | mbedtls_ecp_group_id | grpid, |
size_t * | bits ) |
Convert an ECC curve identifier from the Mbed TLS encoding to PSA.
grpid | An Mbed TLS elliptic curve identifier (MBEDTLS_ECP_DP_xxx ). | |
[out] | bits | On success the bit size of the curve; 0 on failure. |
PSA_ECC_FAMILY_xxx
). This holds even if the curve is not supported by the ECP module. 0
if the curve is not supported in the PSA API. int mbedtls_ecdsa_der_to_raw | ( | size_t | bits, |
const unsigned char * | der, | ||
size_t | der_len, | ||
unsigned char * | raw, | ||
size_t | raw_size, | ||
size_t * | raw_len ) |
Convert an ECDSA signature from DER ASN.1 format to raw format.
bits | Size of each coordinate in bits. | |
der | Buffer that contains the signature in DER format. | |
der_len | Size of der in bytes. | |
[out] | raw | Buffer that will be filled with the converted raw signature. It can overlap with der buffer. |
raw_size | Size of raw in bytes. Must be at least 2 * PSA_BITS_TO_BYTES(bits) bytes. | |
[out] | raw_len | On success it is updated with the amount of valid data (in bytes) written to raw . It's undefined in case of failure. |

Convert an ECDSA signature from raw format to DER ASN.1 format.
bits | Size of each coordinate in bits. | |
raw | Buffer that contains the signature in raw format. | |
raw_len | Length of raw in bytes. This must be PSA_BITS_TO_BYTES(bits) bytes. | |
[out] | der | Buffer that will be filled with the converted DER output. It can overlap with raw buffer. |
der_size | Size of der in bytes. It is enough if der_size is at least the size of the actual output. (The size of the output can vary depending on the presence of leading zeros in the data.) You can use MBEDTLS_ECDSA_MAX_SIG_LEN(bits ) to determine a size that is large enough for all signatures for a given value of bits . | |
[out] | der_len | On success it contains the amount of valid data (in bytes) written to der . It's undefined in case of failure. |

This function returns the PSA algorithm identifier associated with the given digest type.
md_type | The type of digest to search for. Must not be NONE. |

, this function will not return PSA_ALG_NONE
, but an invalid algorithm.md_type
, regardless of whether it is supported or not. Definition at line 121 of file psa_util.h.
