Method Detail

isSupported

public static boolean isSupported()

Returns true if the RsaSsaPkcs1 signature verification using Conscrypt works.

toRsaSsaPkcs1Algo

public static String toRsaSsaPkcs1Algo(RsaSsaPkcs1Parameters.HashType hashType)
                                throws GeneralSecurityException

Throws:

GeneralSecurityException

create

public static PublicKeyVerify create(RsaSsaPkcs1PublicKey key)
                              throws GeneralSecurityException

Returns a new instance of PublicKeyVerify for RsaSsaPkcs1 that uses Conscrypt.

If Conscrypt is not available, this will throw a GeneralSecurityException.

If FIPS mode is enabled but BoringCrypto is not available, this will throw a GeneralSecurityException.

Throws:

GeneralSecurityException

verify

public void verify(byte[] signature,
                   byte[] data)
            throws GeneralSecurityException

Description copied from interface: PublicKeyVerify

Verifies whether signature is a valid signature for data.

Specified by:

verify in interface PublicKeyVerify

Throws:

GeneralSecurityException - if signature is not a valid signature for data
