Secure Password Vault is an app that can store all of your passwords and credit cards in a secure way. Entries are stored in an encrypted file using military-grade 128-bit AES encryption. Additional protections have been added to protect against brute-force and rainbow table attacks.
This app does not require any special permissions beyond write to external storage, especially not full internet access like others do.
Your password file can be backed up so you can easily restore the data later. The backup file is also encrypted rendering the file practically useless to anybody who gets their hands on it. The backup feature works really well if you have Dropbox installed. Otherwise you can backup the file by emailing it to yourself through Gmail or any other app that supports the share intent.
Entries are searchable, simply click the search button on your android device. Note: The passwords themselves are not searched only the other metadata like names, hints, urls, usernames, etc.
Finally, it includes a password generator. Simply select the desired length and types and out comes a completely random password.
New versions will include additional data types like notes.
My day job involves computer security and protecting sensitive data. I wrote this app based on those experiences mostly for myself. Hopefully others find it useful as well.
