LittleSecrets is a generalized password manager. You can entrust notes of any kind to LittleSecrets and save them encrypted on your hard disk. It's up to you for which purpose you use LittleSecrets, e. g. storing passwords, account numbers, provider data, serial numbers, project ideas, URLs etc. LittleSecrets keeps your information in a safe place. It takes care that the only person who gets access to that data is you.
The documents created with LittleSecrets will be encrypted with the so-called Blowfish algorithm with a key length of 448 bit in “Cipher Block Chaining” mode. Therefore you have to choose a password. This method ensures the protection of your data. Only the one who knows the right password will be able to decrypt the information.
Tip: If you put your LittleSecrets document(s) in a private Dropbox folder you always have an off-site backup and you can share the same document on multiple Macs.
LittleSecrets was one of my first Cocoa projects started back in 2001. Although I don't put that much work in this project anymore I still keep it up to date and it's still running fine and used a lot. I use it every day for myself. If you're looking for an iPhone version of LittleSecrets please take a look at Secrets.
