Expand description

Verify the signature sgnt of a message msg.

@param a Hash algorithm to use. Allowed values for a are …

  • Spec_Hash_Definitions_SHA2_256,
  • Spec_Hash_Definitions_SHA2_384, and
  • Spec_Hash_Definitions_SHA2_512. @param modBits Count of bits in the modulus (n). @param eBits Count of bits in e value. @param pkey Pointer to public key created by Hacl_RSAPSS_new_rsapss_load_pkey. @param saltLen Length of salt. @param sgntLen Length of signature. @param sgnt Pointer to sgntLen bytes where the signature is read from. @param msgLen Length of message. @param msg Pointer to msgLen bytes where the message is read from.

@return Returns true if and only if the signature is valid.
