#6 Update french translations

[Guy Teube]

Hi there,
I've made a PR to fix some words in french translation. I've seen this repo on Sourceforge after making the PR.
If the development is still active (I use ccrypt everyday), please see this link:

Best regards

Thanks. The git repo you modified seems to be a snapshot of an (even) older version of ccrypt. I have made the update ("(dé)chiffrage" -> "(dé)chiffrement.") in my upstream version. Ccrypt is infrequently released since it basically doesn't change, so I'm not sure when release 1.12 will come out.
