Keychain support

[aonez]

As in old ticket: http://trac.kekaosx.com/ticket/30

• Support multiple passwords stored in Keychain
  • Suggest them in the password field, compression and extraction (@Holger-Issle List of recent passwords #468)
  • Option to try the stored passwords in extraction (not very efficient?) (@Holger-Issle List of recent passwords #468)
• Add a default password option in preferences (@own2pwn Encrypt by default #118)
• Add context menu support for encryption with default passwords
• Add context menu support for encryption with custom passwords
• Remember password used for files using a fingerprint (i.e. MD5 or SHA256) (@MaxPower85)
• Add a list in plain text of used passwords (and be able to costumize it) (@finalcreator [REQ] remember the compression and decompression password #1048)

Would be great if it were not for keychain, since many times the passwords do not want to have them on my keychain because they are files that I share, with 20-30 passwords saved would be fine
example:
Thanks :)

@ralts00 I won't ask you about the web sites of those passwords... 😒

@aonez
Since each encrypted archive can have it's own password and the user could later rename the file or move it somewhere else (so it could be difficult for the user to keep track of passwords for his archives based on the paths), I guess the simplest way for the user to keep track of his passwords for multiple archives would be to look at the SHA-256 or MD5 or something like that and use that like it's some sort of a "username" in a keychain.

@MaxPower85 I was not planning on making a per file password, but actually I like the idea of the "file fingerprint" using md5 👍

Just manage passwords like BetterZip
