Typedefs
using	crypto::weak::VerifierRs1 = DsaVerifier<DsaType::kRsa, DigestSize::k160>
	Verifies RSASSA signature using SHA-1 and PKCS1 padding.
using	crypto::weak::VerifierPs1 = DsaVerifier<DsaType::kRsaPss, DigestSize::k160>
Verifies HMAC SHA MAC.
using	crypto::VerifierHs1 = HmacShaVerifier<DigestSize::k160>
using	crypto::VerifierHs256 = HmacShaVerifier<DigestSize::k256>
using	crypto::VerifierHs384 = HmacShaVerifier<DigestSize::k384>
using	crypto::VerifierHs512 = HmacShaVerifier<DigestSize::k512>
Verifies RSASSA signature using SHA-2 and PKCS1 padding.
using	crypto::VerifierRs256 = DsaVerifier<DsaType::kRsa, DigestSize::k256>
using	crypto::VerifierRs384 = DsaVerifier<DsaType::kRsa, DigestSize::k384>
using	crypto::VerifierRs512 = DsaVerifier<DsaType::kRsa, DigestSize::k512>
Verifies ECDSA as per RFC7518.
OpenSSL generates ECDSA signatures in ASN.1/DER format, RFC7518 specifies signature as a concatenation of zero-padded big-endian (R, S) values.
using	crypto::VerifierEs256 = DsaVerifier<DsaType::kEc, DigestSize::k256>
using	crypto::VerifierEs384 = DsaVerifier<DsaType::kEc, DigestSize::k384>
using	crypto::VerifierEs512 = DsaVerifier<DsaType::kEc, DigestSize::k512>
Verifies RSASSA signature using SHA-2 and PSS padding as per RFC7518.
JWA specifications require using MGF1 function with the same hash function as for the digest and salt length to be the same size as the hash output.
using	crypto::VerifierPs256 = DsaVerifier<DsaType::kRsaPss, DigestSize::k256>
using	crypto::VerifierPs384 = DsaVerifier<DsaType::kRsaPss, DigestSize::k384>
using	crypto::VerifierPs512 = DsaVerifier<DsaType::kRsaPss, DigestSize::k512>
