SHA-256 Certificate Viewer

View the SHA-256 fingerprints of certificates in the Mozilla Certificate Viewer. Version 0.3 (released November 30, 2012) supports copying in three formats (plain hexadecimal characters, cert URN format, and legacy Mozilla hexadecimal characters with colons), and “Ctrl+C” (keyboard shortcut) copying. Keyboard shortcut copying is localized, so use the same shortcut that you would use in your native language.
