I received a request to add support for --textmode to GPGee and did so. I'm about to release a new version and am updating the help file, and I find that I don't have a clear understanding myself of exactly what --textmode does. I'm hoping someone can explain a few things.
The man page for GnuPG states: -t, --textmode Treat input files as text and store them in the OpenPGP canonical text form with standard "CRLF" line endings. The only time this would seem to matter is with clearsigning, as that is the only time GnuPG writes an input file to its output as text. So, I did the following on a Linux box: $ gpg --clearsign --textmode test1.txt The output was stored as test1.txt.asc, but didn't have CRLF line endings. The line endings were still native Linux LF-only like the source file. So, if --textmode doesn't convert to CRLF during clearsigning, when does it convert? Also, I noticed when searching for information, some sample command lines given with --textmode and --detach-sign. What is the purpose of textmode for a detached signature? The man page further explains that --textmode sets a text flag in the message. Does a detached signature have this text flag? Is any sort of conversion done on the original file during verification of a detached signature? Thanks.
