mbedtls_pk_sign() function
Make signature, including padding if relevant.
Syntax
Return value
0 on success, or a specific error code.
Notes
For RSA keys, the default padding type is PKCS#1 v1.5. There is no interface in the PK module to make RSASSA-PSS signatures yet. If hash_len is 0, then the length associated with md_alg is used instead, or an error returned if it is invalid. For RSA, md_alg may be MBEDTLS_MD_NONE if hash_len != 0. For ECDSA, md_alg may never be MBEDTLS_MD_NONE.
