Hai, I found VarExpandCrypt plugin but not sure the usecase? Somewhere is
more documentation for it? https://wiki2.dovecot.org/Plugins/VarExpandCrypt

Hi!

var_expand_crypt plugin can be used for decrypting/encrypting variables.

It's most common usecase would be to decrypt user credentials encrypted using reversible encryption (a.k.a. obfuscation).

It can be used for other purposes too, like transmitting information from proxy to backend encrypted without using SSL.
