|Base 64 encoding and decoding|
The calculators encode string to base64 string and decode back to original string. Special characters (+/) , generally produced by base64 algorithm, can be replaced by the data provided in additional parameter.
|Rail fence cipher|
This article contains two calculators, first can be used to encode message with the rail fence cipher, second can be used to crack message encoded with the rail fence cipher by brute force. Decoded simply outputs decoded message for different number of "rails".
