Constructors

CryptosignAuthentication(SigningKey privateKey, String? channelBinding)

This is the default constructor that will take an already gathered privateKey integer list to initialize the cryptosign authentication method.

CryptosignAuthentication.fromBase64(String base64PrivateKey)

This method takes a given base64PrivateKey to make crypto sign possible. This key needs to generated to be used with the ed25519 algorithm

factory

CryptosignAuthentication.fromHex(String? hexPrivateKey)

This method takes a given hexPrivateKey to make crypto sign possible. This key needs to generated to be used with the ed25519 algorithm

factory

CryptosignAuthentication.fromOpenSshPrivateKey(String openSshFileContent, {String? password})

This method takes a openSshFileContent and reads its private key to make the authentication process possible with crypto sign. The openSshFileContent must have a ed25519 key file. If the file was password protected, the optional password will decrypt the private key.

factory

CryptosignAuthentication.fromPuttyPrivateKey(String ppkFileContent, {String? password})

This method takes a ppkFileContent and reads its private key to make the authentication process possible with crypto sign. The ppkFileContent must have a ed25519 key file. If the file was password protected, the optional password will decrypt the private key.

Methods

challenge(Extra extra) → Future<Authenticate>

This method is called by the session if the router returns the challenge or the challenges extra respectively. This method uses the passed hex encoded challenge and signs it with the given private key

override

getName() → String

This method is called by the session to identify the authentication name.

override

hello(String? realm, Details details) → Future<void>

This method is called by the session to modify the hello details for a given realm. Cryptosign will add a 'pubkey' and a 'channel_binding' to the authextra

override

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

toString() → String

A string representation of this object.

Operators

operator ==(Object other) → bool

The equality operator.

Static Methods

decodePpkPrivateKey(List<int> encryptedPrivateKey, String password) → Uint8List

This method takes a encryptedPrivateKey and decrypts it by useing the provided password.

hexToBin(String? hexString) → Uint8List

This method converts a given hexString to its byte representation.

loadPrivateKeyFromOpenPCKS1Pem(String pemFileContent) → void

loadPrivateKeyFromOpenPCKS8Pem(String pemFileContent) → void

loadPrivateKeyFromOpenSSHPem(String pemFileContent, {String? password}) → Uint8List

Loads a private key from a pemFileContent that has been encoded with the open ssh file format:

loadPrivateKeyFromPpk(String? ppkFileContent, {String? password}) → Uint8List

This helper method takes a ppkFileContent and its password and extracts the private key into a list.

ppkMacCheck(String? privateMac, PpkMacData macData, String? password) → void

This method performs the mac check against the privateMac to validate the files content. It is also capable of testing whether the password was wrong or not. The macData is data used to compute the mac and to compare it to the given privateMac
