Base64

Base 64 as used in Freenet

Freenet uses a variant of Base 64 encoding for its keys to convert a block of bytes (for example a hash) into a URI component.

The encoding we use consists of:

• The characters A-Z
• The characters a-z
• The characters 0-9
• The character ~
• The character -

This is an unusual variant according to Wikipedia, but it is used by other apps than Freenet.

It is implemented in src/freenet/support/Base64.java.
