Hi, I try to decrypt some string. Does this code looks good? I get error: CryptoKit.CryptoKitError error 3. do { guard let encryptedData = Data(base64Encoded: cardNumber), let securityKeyData = Data(base64Encoded: securityKey), let ivData = Data(base64Encoded: iv), let privateKeyData = Data(base64Encoded: privateKey) else { throw NSError(domain: "invalid_input", code: 1, userInfo: [NSLocalizedDescriptionKey: "Invalid Base64 input."]) } let privateKey = try P256.KeyAgreement.PrivateKey(derRepresentation: privateKeyData) let publicKey = try P256.KeyAgreement.PublicKey(derRepresentation: securityKeyData) let sharedSecret = try privateKey.sharedSecretFromKeyAgreement(with: publicKey) let symmetricKey = sharedSecret.hkdfDerivedSymmetricKey( using: SHA256.self, salt: Data(), sharedInfo: Data(), outputByteCount: 32 ) let encryptedDataWithoutTag = encryptedData.dropLast(16) let tagData = encryptedData.suffix(16) let nonce = try AES.GCM.Nonce(data: ivData) let sealedBox = try AES.GCM.SealedBox(nonce: nonce, ciphertext: encryptedDataWithoutTag, tag: tagData) let decryptedData = try AES.GCM.open(sealedBox, using: symmetricKey) resolve(decryptedCardNumber) } catch { print("Decryption failed with error: \(error.localizedDescription)") reject("decryption_error", "Decryption failed with error: \(error.localizedDescription)", nil) }
