LS47 Cipher
Password
Padding
Signature
LS47 Cipher is a slight improvement of the ElsieFour cipher as described by Alan Kaminsky. It use 7x7 characters instead of original (barely fitting) 6x6, to be able to encrypt some structured information. It also describe a simple key-expansion algorithm, because remembering passwords is popular.
Similar security considerations as with ElsieFour hold.
The LS47 alphabet consists of following characters: _abcdefghijklmnopqrstuvwxyz.0123456789,-+*/:?!'()
A LS47 key is a permutation of the alphabet that is then represented in a 7x7 grid used for the encryption or decryption.
