REDACT(1)

 

NAME

redact - an obfuscation utility  

SYNOPSIS

redact (option [option-arg]) ...  

DESCRIPTION

redact can encode or decode strings. It is NOT secure, as it uses an easily breakable algorithm. Yet, it provides a consistent way to obfuscate some tokens without losing the possibility to retrieve their original values. The items that this tool is meant to obfuscate, such as authenticated user-id's, may be considered correct, even de rigueur, to divulge. However, they can be abused by unethical people. For example, knowing the user id may aid password cracking.

The core function of this program is statically linked inside the zdkimfilter executable, and dynamically linked with libnettle.

--encode clearstring
