Examples of org.apache.commons.codec.binary.Base32

org.apache.commons.codec.binary.Base32
etf.org/rfc/rfc4648.txt">RFC 4648.
The class can be parameterized in the following manner with various constructors:
- Whether to use the "base32hex" variant instead of the default "base32"
- Line length: Default 76. Line length that aren't multiples of 8 will still essentially end up being multiples of 8 in the encoded data.
- Line separator: Default is CRLF ("\r\n")
This class operates directly on byte streams, and not character streams.

This class is thread-safe.
