FAQ
How can I use AES encryption and decryption?
const SecretKey = TBytes.Create($0, $1, $2, $3, $4, $5, $6, $7, $8, $9, $A, $B, $C, $D, $E, $F);
const InitializationVector = TBytes.Create($F, $E, $D, $C, $B, $A, $9, $8, $7, $6, $5, $4, $3, $2, $1, $0);
var CipherText: TBytes;
// AES encryption
with TSymmetricKey.Create(TSymmetricKeyAlgorithm.skAES, TChainingMode.cmCBC, SecretKey) do
try
IV := InitializationVector;
CipherText := Encrypt('Hello, world!');
finally
Free;
end;
// AES decryption
with TSymmetricKey.Create(TSymmetricKeyAlgorithm.skAES, TChainingMode.cmCBC, SecretKey) do
try
IV := InitializationVector;
const PlainBytes = Decrypt(CipherText);
const PlainText = TEncoding.UTF8.GetString(PlainBytes);
ShowMessage(PlainText);
finally
Free;
end;
