SHA-256, 384 or 512 for Thunderbird’s Enigmail

by

SHA-1 is the default hash algorithm for Thunderbird’s Enigmail. As it looks like SHA-1 isn’t secure anymore you should use at least SHA-256 which might be the future standard algorithm. Here is what you need to do:

Start Thunderbird, click Edit -> Preferences. Go to the Config Editor. Locate extensions.enigmail.mimeHashAlgorithm. Set the value to 3, 4 or 5. Default is 0 which means SHA-1. If you set it to 3 Enigmail will use SHA-256, 4 means SHA-384 and 5 SHA-512. If you set the value to 2 Enigmail will use RIPEMD-160. Not a bad choice either.
