+If Emacs crashed and dumps core, passphrase strings in memory are also
+dumped with the core file. `read-passwd' function clears passphrase
+strings by `(fillarray string 0)'. However, it is not perfect. Emacs
+does compaction of small strings in gc_sweep phase. If GC happens
+before `fillarray', passphrase strings may be copied elsewhere in
+memory. So, it is recommended that if you are done with passphrase
+you should clear it manually. However, PGG and gpg.el enables
+passphrase caching by default.

+As the name indicates, EasyPG is inspired by GPGME (GnuPG Made Easy),
+and the library interface is close to GPGME.
