DecryptAesCbc ( byte ciphertext, byte key, byte iv = null, bool checkAndRemoveHmac = false ) : byte[]	Decrypt a message using AES in CBC (cipher-block chaining) mode.
DecryptAesCbcEncryptedEcPrivateKey ( byte ecPrivateKeyEncryptedWithAesCbc, byte symmetricKey ) : System.Security.Cryptography.ECDiffieHellmanCng	Decrypt an EC private key that has been stored encrypted with AES CBC using a private key
DecryptAesCbcEncryptedPrivateKey ( byte privateKeyEncryptedWithAesCbc, byte symmetricKey ) : IPrivateKey	Decrypt an EC private key that has been stored encrypted with AES CBC using a private key
DecryptAescbcutf8 ( byte ciphertext, byte key, byte iv = null, bool checkAndRemoveHmac = false ) : string
EncryptAesCbc ( byte plaintext, byte key, byte iv = null, bool addHmac = false ) : byte[]	Encrypt a message using AES in CBC (cipher-block chaining) mode.
EncryptAesCbc ( string plainText, byte key, byte iv = null, bool addHmac = false ) : byte[]
EncryptEcPrivateKeyWithAesCbc ( System.Security.Cryptography.ECDiffieHellmanCng ecPrivateKey, byte symmetricKey ) : byte[]	Encrypt an EC private key with a symmetric key.
EncryptPrivateKeyWithAesCbc ( IPrivateKey privateKey, byte symmetricKey ) : byte[]	Encrypt an EC private key with a symmetric key.
GenerateNewPrivateKey ( ) : IPrivateKey
GetPublicKeyFromByteArray ( byte publicKeyAsByteArray ) : IPublicKey
KeyGenFromPwd ( string password, byte salt ) : byte[]	Generate key from hashed password. We will need to use stronger hash later.

Decrypt a message using AES in CBC (cipher-block chaining) mode.

public static DecryptAesCbc ( byte ciphertext, byte key, byte iv = null, bool checkAndRemoveHmac = false ) : byte[]
ciphertext	byte	The message encrypted with AES in CBC mode
key	byte	The key used to encrypt the message
iv	byte	The initialization vector provided, if one was provided. If you are absolutely certain /// the key will only be used once, an IV is not necessary and zero will be used.
checkAndRemoveHmac	bool	Set if an HMACHSA256 was placed at the end of the plaintext before encrypting. /// The HMAC will be removed before the plaintext is returned. If the HMAC does not match, the method will throw a /// System.Security.Cryptography.CryptographicException.
Résultat	byte[]

public static DecryptAesCbcEncryptedEcPrivateKey ( byte ecPrivateKeyEncryptedWithAesCbc, byte symmetricKey ) : System.Security.Cryptography.ECDiffieHellmanCng
ecPrivateKeyEncryptedWithAesCbc	byte	The EC private key encrypted with AES CBC.
symmetricKey	byte	The symmetric key with which to encrypt the EC key. Must be at least /// 16 bytes. Any additional bytes will be ignored.
Résultat	System.Security.Cryptography.ECDiffieHellmanCng

public static DecryptAesCbcEncryptedPrivateKey ( byte privateKeyEncryptedWithAesCbc, byte symmetricKey ) : IPrivateKey
privateKeyEncryptedWithAesCbc	byte	The assymetric private key encrypted with AES CBC.
symmetricKey	byte	The symmetric key with which to encrypt the EC key. Must be at least /// 16 bytes. Any additional bytes will be ignored.
