Encrypt and decrypt text using AES, DES, and other encryption algorithms.
Encryption/Decryption Tool is a free online utility that lets you encrypt and decrypt text using AES, DES, and other encryption algorithms. It runs entirely in your browser — no account creation, no software installation, and no data uploaded to external servers. This makes it a practical choice for anyone who needs to work with security & privacy tools-related values quickly and privately. Whether you are a professional working through a daily task list, a student checking homework figures, or a freelancer preparing a deliverable, Encryption/Decryption Tool gives you an instant result you can copy, screenshot, or feed into the next step of your workflow. ToolPeg hosts this tool alongside security & privacy tools tools and 300+ other free utilities so you always have a single bookmark for everyday browser-based tasks.
Many ToolPeg tools process inputs locally, but tools that work with public URLs, domains, or network-facing information should still be treated as working with public-facing data.
Generate MD5 hash values for text strings and verify file integrity.
Review SSL/TLS certificate fields and expiry dates with a browser-based educational checker.
Generate SHA-256 cryptographic hashes for secure data verification.
Explore DNS record types and build a reference DNS table in the browser.
Generate terms of service pages tailored to your business needs.
Generate a customized privacy policy for your website or app.
The same password must be used for both encryption and decryption.

About AES-GCM Encryption
This tool uses AES-256-GCM (Galois/Counter Mode) via the Web Crypto API. Your password is converted to a 256-bit key using PBKDF2 with 100,000 iterations. A random salt and initialization vector (IV) are generated for each encryption. The encrypted output contains the salt, IV, and ciphertext combined and encoded in Base64. All processing happens in your browser - nothing is sent to any server.
