Encrypt Decrypt Text2.0.0 - Google Play

In a digital world,
your privacy is non-negotiable.
Whether sharing confidential passwords, storing recovery keys or sending private messages, you need cryptographic security you can verify and trust.

Welcome to
Encrypt Text (EDT)
— the modern privacy utility designed to encrypt, decrypt and manage sensitive text completely offline on your device.

🛡️ Upgraded to Authenticated Encryption (AEAD)
Encrypt Text is built with modern, battle-tested cryptographic standards:

•
AES-256-GCM (Authenticated Encryption):
Uses Galois/Counter Mode (GCM) - the modern cryptographic standard. Unlike legacy AES-CBC, GCM provides both
confidentiality
and
integrity validation
(AEAD). Any tampering or corrupted ciphertext is caught instantly before decryption.
•
Hardened Key Derivation:
Your password is transformed into an encryption key using
PBKDF2 with HMAC-SHA256
and high iteration counts to defend against GPU/ASIC brute-force dictionary attacks.
•
Unique CSPRNG Nonces & Salts:
Every encryption operation generates a fresh, secure 12-byte IV and salt, preventing pattern detection and replay attacks.
•
Legacy Decrypt Migration:
Have text encrypted with older EDT versions? Our built-in Legacy Decrypt engine lets you decode legacy formats and seamlessly re-encrypt them with modern AES-256-GCM.

🔐 Built-in Encrypted Vault & Saved Notes
Turn your encrypted data into a personal, offline confidential vault:
•
Store Encrypted Notes:
Keep passwords, private journal entries, API secrets and sensitive records safe on your device.
•
Biometric Hardware Security:
Lock and unlock individual notes with your
Fingerprint
or
Face Unlock
, backed by Android Keystore hardware protection.
•
Organize with Tags & Search:
Categorize notes with custom tags and instantly filter your vault.
•
Privacy-First CSV Import/Export:
Export your notes using Android's native Storage Access Framework without granting blanket storage permissions.

💡 Perfect For:
•
Private Messaging:
Encrypt messages before sending via email, WhatsApp, Telegram or SMS. Only the recipient with the exact password can decrypt.
•
Credential & Key Storage:
Protect crypto seed phrases, server credentials, 2FA backup codes and private keys.
•
Digital Diary & Thoughts:
Keep personal journals and confidential notes protected.

⚠️ Important Security Notes
•
Your Password is the Only Key:
We follow a strict Zero-Knowledge architecture. We do not store, track or transmit your passwords. If you lose or forget your password,
your encrypted text cannot be recovered by anyone.
•
Exact Match Required:
Decryption requires the exact same password used during encryption.
