Simple Ciphers

A C# package for plain text encryption and decryption for simple, but fun ciphers.

Add to Project

Via dotnet:

dotnet add package simple-ciphers --version 2.1.0

Via PackageReference in your .csproj file:

<PackageReference Include="simple-ciphers" Version="2.1.0" />

Encryption

Use A1Z26() to substitute letters for their corresponding positions.

Encryption.A1Z26("hello world!");
// returns: 8-5-12-12-15 23-15-18-12-4!

Use Atbash() to swap letters to their opposite positions.

Encryption.Atbash("hello world!");
// returns: svool dliow!

Use Caesar() for shift ciphers.

Encryption.Caesar("hello world!", 3);
// returns: khoor zruog!

Use Morse() to substitute letters for their morse code equivalent.

Encryption.Morse("hello world!");
// returns: .... . .-.. .-.. --- / .-- --- .-. .-.. -.. -.-.--

Use Vigenere() to cipher with a key.

Encryption.Vigenere("hello world!", "key");
// returns: rijvs uyvjn!

Decryption

Use A1Z26() to substitute numbers for their corresponding letters.

Decryption.A1Z26("8-5-12-12-15 23-15-18-12-4!");
// returns: hello world!

Use Atbash() to swap letters to their opposite positions.

Decryption.Atbash("svool dliow!");
// returns: hello world!

Use Caesar() for shift ciphers.

Decryption.Caesar("khoor zruog!", 3);
// returns: hello world!

Use Morse() to substitute morse code for their letter and/or symbol equivalent.

Deryption.Morse(".... . .-.. .-.. --- / .-- --- .-. .-.. -.. -.-.--");
// returns: hello world!

Use Vigenere() to decipher with a key.

Encryption.Vigenere("rijvs uyvjn!", "key");
// returns: hello world!
