The Salsa20 component can be used to encrypt and decrypt data with the XSalsa20 and Salsa20 algorithm.

Syntax

TipcSalsa20

Remarks

The component implements XSalsa20 as well as Salsa20. The Algorithm property specifies which algorithm to use when encrypting and decryption. In addition the 12 and 8 round variants of Salsa20 are supported.

Data may be encrypted and decrypted in its entirety by calling Encrypt and Decrypt or chunk by chunk by calling EncryptBlock and DecryptBlock.

In all operations a Key and IV must be used. If IV is not set one is automatically generated. KeyPassword may be set in order to automatically generate both a Key and IV when a method is called. The same KeyPassword, or Key and IV pair are used on both sides of the operation data can be encrypted and decrypted.

Encrypt Notes

Encrypt will encrypt the specified data. The following properties are applicable:

• IV (required)
• Key (required)

Input and Output Properties

The component will determine the source and destination of the input and output based on which properties are set.

The order in which the input properties are checked is as follows:

• SetInputStream
• InputFile
• InputMessage

When a valid source is found, the search stops. The order in which the output properties are checked is as follows:

• SetOutputStream
• OutputFile
• OutputMessage: The output data is written to this property if no other destination is specified.

When using streams, you may need to additionally set CloseInputStreamAfterProcessing or CloseOutputStreamAfterProcessing.

Additional Notes

The Key property must be set to a 256 bit (32 byte) value. This is the only allowed value for ChaCha20. If KeyPassword is set both Key and IV will be automatically generated when Encrypt is called.

The IV must be set to a 192 bit (24 byte) value when Algorithm is set to XSalsa. The IV must be set to a 64 bit (8 byte) value when Algorithm is set to Salsa.

If IV is not set a value will automatically be generated by the component when Encrypt is called.

During encryption the Progress event will fire as data is encrypted.

Encrypt 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 }; salsa.InputMessage = "hello salsa!"; salsa.Encrypt(); //salsa.OutputMessageB contains the byte[] of the encrypted data. The above code produces the following encrypted bytes. // { 0x06, 0xF4, 0xD9, 0xB4, 0x67, 0x31, 0x1C, 0x1E, 0x8E, 0xD6, 0xB5, 0x6B }

Encrypt Block Notes

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);

Decrypt Notes

Decrypt will decrypt the specified data. The following properties are applicable:

• IV (required)
• Key (required)

Input and Output Properties

The component will determine the source and destination of the input and output based on which properties are set.

The order in which the input properties are checked is as follows:

• SetInputStream
• InputFile
• InputMessage

When a valid source is found, the search stops. The order in which the output properties are checked is as follows:

• SetOutputStream
• OutputFile
• OutputMessage: The output data is written to this property if no other destination is specified.

When using streams, you may need to additionally set CloseInputStreamAfterProcessing or CloseOutputStreamAfterProcessing.

Additional Notes

The Key property must be set to the 256 bit (32 byte) value originally used to encrypt the data. IV must be set to the original IV value used to encrypt the data.

If using a password, KeyPassword must be set to the same KeyPassword used when encrypting the data. This will automatically generate both Key and IV when Decrypt is called.

During decryption the Progress event will fire as data is decrypted.

Indicates whether or not the component should overwrite files.

Syntax

property Overwrite: Boolean read get_Overwrite write set_Overwrite;

Default Value

false

Remarks

This property indicates whether or not the component will overwrite OutputFile. If Overwrite is False, an error will be thrown whenever OutputFile exists before an operation. The default value is False.

UseHex Property (Salsa20 Component)

Whether input or output is hex encoded.

Syntax

property UseHex: Boolean read get_UseHex write set_UseHex;

Default Value

false

Remarks

This property specifies whether the encrypted data is hex encoded.

If set to True, when Encrypt is called the component will perform the encryption as normal and then hex encode the output. OutputMessage or OutputFile will hold hex encoded data.
