/**
  Verifies the RSA signature with RSASSA-PSS signature scheme defined in RFC 8017.
  Implementation determines salt length automatically from the signature encoding.
  Mask generation function is the same as the message digest algorithm.
  Salt length should be equal to digest length.

  @param[in]  RsaContext      Pointer to RSA context for signature verification.
  @param[in]  Message         Pointer to octet message to be verified.
  @param[in]  MsgSize         Size of the message in bytes.
  @param[in]  Signature       Pointer to RSASSA-PSS signature to be verified.
  @param[in]  SigSize         Size of signature in bytes.
  @param[in]  DigestLen       Length of digest for RSA operation.
  @param[in]  SaltLen         Salt length for PSS encoding.

  @retval  TRUE   Valid signature encoded in RSASSA-PSS.
  @retval  FALSE  Invalid signature or invalid RSA context.
