Examples

Encoding with one encoder

$ ./pencoder.sh b64 'this is a test'
dGhpcyBpcyBhIHRlc3Q=

$ ./pencoder.sh morse sos
... --- ...

$ ./pencoder.sh bin Xmas
01011000 01101101 01100001 01110011

Decoding with one decoder

$ ./pencoder.sh b64de 'dGhpcyBpcyBhIHRlc3Q='
this is a test

$ ./pencoder.sh morsede '... --- ...'
SOS

$ ./pencoder.sh binde '01001101 01100001 01110100 01110100 01100101 00100000 01000010 01101100 01100001 01100011 01101011 00100000 01000101 01110110 01100101 01110010 01111001 01110100 01101000 01101001 01101110 01100111 00101110'
