EncryptBlock Method

Encrypts data and returns the encrypted block.

function EncryptBlock(InputBuffer: TBytes): TBytes;

Remarks

EncryptBlock will encrypt the input data and return the encrypted block. The encrypted block will always be the same length as the decrypted data. The following properties are applicable:

• IV (required)
• Key (required)

InputBuffer specifies the input data to encrypt.

EncryptBlock Example

Salsa20 salsa = new Salsa20();

//32 Bytes
salsa.KeyB = new byte[] { 0xBB, 0x76, 0x17, 0xC9, 0x05, 0x73, 0x4A, 0x8D, 0x59, 0x9D, 0x7B, 0x0D, 0x86, 0x2A, 0x03, 0x82, 0x50, 0x6A, 0x70, 0xFB, 0xA8, 0x56, 0x47, 0x1B, 0x1E, 0x68, 0x0B, 0x2B, 0x34, 0x18, 0x0F, 0xE2 };

//24 Bytes
salsa.IVB = new byte[] { 0x0D, 0xE4, 0x43, 0x40, 0x29, 0xAD, 0x70, 0x7D, 0x7B, 0x32, 0xB5, 0xC7, 0x0D, 0xE4, 0x43, 0x40, 0x29, 0xAD, 0x70, 0x7D, 0x7B, 0x32, 0xB5, 0xC7 };

byte[] tempEncryptedBlock;
 
//Encrypt any number of blocks of any size
tempEncryptedBlock = salsa.EncryptBlock(part1);
tempEncryptedBlock = salsa.EncryptBlock(part2);
