Note that there is also a method redsys.createMerchantSignatureNotif(key, encoded) available that returns base64 signature
to compare with the original, however due to some base64 differencies it is recommended to use the
redsys.checkMerchantSignatureNotif(key, encoded, signature) method. However if you want to use it, make sure to convert
the original signature as `Buffer.from(signature, 'base64').toString('base64');
