I need an encryption method to encrypt (and decrypt) a contents of a text string  to
a target string which contains only printable characters (or even characters A-Z,a-z,0-9).
How do I do that ?

As far as I know the Jave Encrytion extension JCE doesn't offer such a method.
If I use e.g. Blowfish in JCE it produces a ciphertext which contains Linebreaks (<CR>).
So it is not suitable.

It is not required to be ultra secure.
Does someone know an easy way to accomplish that ?

Thank you
Thorsten

A really easy way would be to base64 encode the encrypted String.  Of
course, if you just want to obfuscate the String you could just use
the base64 encoding to start with and be done with it.
