optimizing pass phrase match check / decrypt sequence

[tomholub]

We pass array of keys [key1-longid1, key2-longid2, key3-longid3] to parse parseDecryptMsg in

let decrypted = try self.core.parseDecryptMsg(
                encrypted: rawMimeData,
                keys: keys,
                msgPwd: nil,
                isEmail: true
)

If I get longid for the key which was used to decrypt a message I can save PassPhrase with proper longid here

keys
  .map { PassPhrase(value: passPhrase, longid: $0.longid) }
  .forEach { self.passPhraseStorage.savePassPhrase(with: $0, inStorage: false) }

Actually it's the same question as below - are there any possibility to check that entered pass phrase is matching particular key before I try to decrypt a message and check the error?
