PasswordManager

A secure, encrypted command-line password manager built with Rust.

Features

• AES-256-GCM encryption with Argon2 key derivation
• Random salt and nonce per vault
• Master password never stored on disk
• CLI commands: add, get, list, delete
• Hidden password input and optional reveal

Install

Prereq: Rust 1.74+.

cargo build --release
# binary: target/release/PasswordManager

Optional global install:

cargo install --path .

Usage

# add (prompt for password)
cargo run -- add github --username user@example.com

# list
cargo run -- list

# get (hidden by default)
cargo run -- get github

# reveal password
cargo run -- get github --show

Security Notes

Protects against encrypted file theft, tampering, and offline brute-force attempts. Does not protect against malware/keyloggers, weak master passwords, or a machine that is already unlocked.

Development

cargo run --example demo
cargo fmt
cargo clippy

Files
