Encrypt and decrypt text with AES-256-GCM using your own password. Share the encrypted text and the password separately — only someone with the password can read it.
The Encrypt & Decrypt Text tool by TooliFyra provides client-side text encryption using industry-standard AES-256-GCM encryption, with your password turned into a key by PBKDF2-SHA256 (150,000 iterations). Protect sensitive information, create encrypted messages, or decrypt received data — all without any server processing.
Encryption converts readable text (plaintext) into an unreadable format (ciphertext) using a secret key. Only someone with the correct key can decrypt the message back to readable text.
Client-side encryption ensures your sensitive data never leaves your device. The Encrypt & Decrypt Text tool is ideal for securing messages before sharing, protecting configuration data, or learning about encryption concepts.
Security Professionals: Quick text encryption for secure communication.
Developers: Encrypt configuration values, API keys, or sensitive data in code.
Journalists: Protect sensitive information and sources.
General Users: Encrypt personal notes, passwords, or private messages.
TooliFyra uses the Web Crypto API for AES-256 encryption, providing the same level of security as professional encryption tools. Your data is processed entirely in your browser — no keys, plaintext, or ciphertext ever leaves your device.
AES-256 is recommended for most use cases. It is the industry standard for symmetric encryption and is used by governments worldwide.
Yes. The encryption happens in your browser using the Web Crypto API, which uses the same cryptographic primitives as native OS encryption.
Without the correct key, encrypted text cannot be decrypted. There is no recovery mechanism — this is by design for security.
