Examples with EncryptionIdentifier org.firebirdsql.gds.ng.wire.crypt.EncryptionIdentifier used on opensource projects

Example 1 with EncryptionIdentifier

use of org.firebirdsql.gds.ng.wire.crypt.EncryptionIdentifier in project jaybird by FirebirdSQL.

the class V13WireOperations method enableEncryption.

protected void enableEncryption(EncryptionInitInfo encryptionInitInfo) throws SQLException, IOException {
    final XdrInputStream xdrIn = getXdrIn();
    final XdrOutputStream xdrOut = getXdrOut();
    final Encoding encoding = getEncoding();
    final EncryptionIdentifier encryptionIdentifier = encryptionInitInfo.getEncryptionIdentifier();
    xdrOut.writeInt(op_crypt);
    xdrOut.writeString(encryptionIdentifier.getPluginName(), encoding);
    xdrOut.writeString(encryptionIdentifier.getType(), encoding);
    xdrOut.flush();
    xdrIn.setCipher(encryptionInitInfo.getDecryptionCipher());
    xdrOut.setCipher(encryptionInitInfo.getEncryptionCipher());
    readOperationResponse(readNextOperation(), null);
}
