Peach for Android

A free, open source, local-first password manager for Android.

No accounts. No subscription. Your passwords stay on the device, encrypted with AES-256-GCM and protected by Argon2id key derivation. Sync, backup, and autofill happen without trusting any cloud in the middle.

Features

• Zero-knowledge vault — AES-256-GCM encryption, Argon2id KDF, keys never leave your device
• End-to-end encrypted sync — pairs with your other Peach devices over a Noise channel; the relay only forwards ciphertext it cannot read
• Inline autofill — fills directly in apps, no copy-paste detour
• Passkeys — WebAuthn credentials alongside your passwords
• Quick Settings tile — copy a credential from anywhere with a single tap
• Biometric unlock — hardware-backed AndroidKeyStore escrow, invalidated on enrollment change
• Codex — prints your encrypted vault as Aztec codes on paper. Physical offline backup

Open Source

Peach is free and open source under the GPL v3 license. Both the browser extension and the Android app.

The source is hosted on Kepr — Asha Software's own version control platform.

Security

Peach has undergone two adversarial analysis sessions against this codebase. The most recent findings have been resolved.

Cryptographic primitives:

• Key derivation: Argon2id (m=64MiB, t=3, p=4)
• Encryption: AES-256-GCM with fresh random nonces
• Sync handshake: Noise NK / Noise KK (25519, ChaChaPoly, BLAKE2s)
• Backup codec: GF(2⁸) Reed-Solomon with zstd compression
• BLAKE3 checksums throughout

The canonical Noise core lives in a shared Rust crate with the browser extension — Android drives it via JNI. See docs/CRYPTOGRAPHIC-TEST-VECTORS.md for the byte-level vectors that pin each primitive.

Building

./gradlew assembleRelease

Outputs to app/build/outputs/apk/release/. The shared Noise core is built from ../peach-browser/crypto-core.
