Method Detail

toRsaSsaPkcs1Algo

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

Throws:

java.security.GeneralSecurityException

create

public static PublicKeyVerify create(RsaSsaPkcs1PublicKey key)
                              throws java.security.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:

java.security.GeneralSecurityException

createWithProvider

public static PublicKeyVerify createWithProvider(RsaSsaPkcs1PublicKey key,
                                                 java.security.Provider conscrypt)
                                          throws java.security.GeneralSecurityException

Throws:

java.security.GeneralSecurityException

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

Description copied from interface: PublicKeyVerify

Verifies whether signature is a valid signature for data.

Specified by:

verify in interface PublicKeyVerify

Throws:
