<<LITEVAULT
Author: Luis G.L.
Program: LiteVault
Description:
Program that performs Vault tasks for username/password storage
Symmetric key file encryption is used:
GPG symmetrically encrypted data (AES256 cipher)
ChangeLog:
v1.0: Encryption + Decryption and listing accounts
v1.5: Token management and user creation
v2.0: Account creation and deletion
v2.5: Full CRUD
v2.7: Variable setting and error code output
v2.9: Inclusion of masterkey to open LiteVault
v3.0: Check empty MasteKey and different CyPass per user
v3.1: Show TOKEN chunk to facilitate search
v3.2: Now you only need the TOKEN and the MasterKey to manage accounts
-------------------------------------------------------------------------------------------------------
.LiteVault file format (always in the home of the user who launches it)
_______________________________________
account account.name #Token (unique value)
login User
password UserPassword
account account.name #Token (unique value)
login User
password UserPassword
(...)
_______________________________________
-------------------------------------------------------------------------------------------------------
NOTES AND STEPS:
1) To generate CyPass (internal encryption key) use
gpg --gen-random --armor 1 50| tr -dc 'A-za-z0-9';echo
1.a) Replace 'INTERNALCIPHERKEY' with the value obtained in CyPass
2.b) Store the CyPass value in a safe place (for emergencies only)
2) Compile and obfuscate this script using the shc program:
shc -r -f LiteVault.sh -o LiteVault
3) Use only the binary program created and delete the script
