```text
Install-Package Cosmos.Security.Encryption
```
## Includes
- MD2
- MD4
- MD5
- SHA1/256/384/512
- SM3
- HMAC
- MurmurHash2
- MurmurHash3
- Time33/DBJ33A

## Usage
HAMC-SHA1:
```c#
var signature = HMACSHA1HashingProvider.Signature("image", "alexinea");
```
DES without salt:
```c#
var s = DESEncryptionProvider.Encrypt("image", "alexinea", "forerunner");
Assert.Equal("fJ2yrnAPaH0=", s);
var o = DESEncryptionProvider.Decrypt(s, "alexinea", "forerunner");
Assert.Equal("image", o);
```
DES with salt:
```c#
var s = DESEncryptionProvider.Encrypt("image", "alexinea", "forerunner", "123412341234");
Assert.Equal("s4h5u8hA/2Y=", s);
var o = DESEncryptionProvider.Decrypt(s, "alexinea", "forerunner", "123412341234");
Assert.Equal("image", o);
```
DES with salt and autokey
```c#
var key = DESEncryptionProvider.CreateKey();
var s = DESEncryptionProvider.Encrypt("image", key.Key, key.IV, "123412341234");
var o = DESEncryptionProvider.Decrypt(s, key.Key, key.IV, "123412341234");
Assert.Equal("image", o);
```
