\brief This function performs a PKCS#1 v1.5 verification operation (RSASSA-PKCS1-v1_5-VERIFY).

\param ctx The initialized RSA public key context to use. \param md_alg The message-digest algorithm used to hash the original data. Use #MBEDTLS_MD_NONE for signing raw data. \param hashlen The length of the message digest or raw data in Bytes. If \p md_alg is not #MBEDTLS_MD_NONE, this must match the output length of the corresponding hash algorithm. \param hash The buffer holding the message digest or raw data. This must be a readable buffer of at least \p hashlen Bytes. \param sig The buffer holding the signature. This must be a readable buffer of length \c ctx->len Bytes. For example, \c 256 Bytes for an 2048-bit RSA modulus.

\return \c 0 if the verify operation was successful. \return An \c MBEDTLS_ERR_RSA_XXX error code on failure.
