<p dir="auto">Hi,</p>
<p dir="auto">About SHA-1 had been just a thread:<br>
: [MlMt] Note that the SHA1 hash algorithm has been found to have weaknesses<br>
What works for me, was recreating all subways and then in gpg.conf:<br>

<p dir="auto">Hi,</p>
<p dir="auto">I am using MM with GPG and it works, but uses the outdate SHA-1 and not SHA-256. I have not had this problems when using command line GPG or with any other email client. Anyone knowing the source of the problem and how this could be fixed?</p>
<p dir="auto">The GPG was installed using homebrew and have the setting:</p>
<p dir="auto">defaults write com.freron.MailMate environmentVariables -array '{ enabled = :true; name = "MM_GPG"; value = "/opt/homebrew/bin/gpg"; }'</p>
<p dir="auto">The ‘OpenPGP: Signed’ says:<br>
/opt/homebrew/bin/gpg --no-verbose --batch --no-tty --compliance "openpgp" status-fd 2 --textmode --armor --local-user "<a href="mailto:staffan.persson@atsec.com" style="color: #777777;">staffan.persson@atsec.com</a>" detach-sign</p>
