I have an old
encrypted file with a .cpt extension. I created this file using an old
version of SuSE if memory serves. I am trying to figure out how to figure
out what utility/algorithm was used to create this file so I can take some stabs
at decrypting it. The file in question was a tar.gz file that was
encrypted using some console based encryption program (with a command like
"encrypt filename.ext" which produces "filename.ext.cpt"), which may help
determine this. Is there maybe a utility that would allow me to put in a
password and have it try to decrypt using all known algorithms and perhaps show
the first few lines from the decrypted file (so I can determine if one looks
like a gz file - although I haven't looked to see if it would have a
recognizable header)?
I'm just trying to
figure out how to proceed at this point, of if I can forget getting the data
contained in this file back.
