From http://www.gpg4win.org/doc/en/gpg4win-compendium_15.html >If the public certificate was mailed as a block of text that was included in the e-mail, you have to highlighte the entire certificate: >In the case of (public) OpenPGP certificates, please highlight the area from >---BEGIN PGP PUBLIC KEY BLOCK--- >up to >---END PGP PUBLIC KEY BLOCK--- >just as we have seen in Section 8.1. >Now use Copy & Paste to insert the highlighted section into a text editor and save the public certificate. For file endings, you should use .asc or .gpg for OpenPGP certificates and .pem or .der for X.509 certificates. This is pretty annoying and involves another program. It would be nice if it was possible to import certificate from clipboard, or maybe a textarea to paste in. Reproducible: Always
