What is Text Encryption and Hashing?

A hash function is an algorithm that maps data of arbitrary length to a fixed-length digest. Common hash algorithms include MD5, SHA1, SHA256, SHA512, and others. Hash functions have the following properties:

One-way: The original data cannot be recovered from the hash value
Deterministic: The same input always produces the same hash value
Collision-resistant: It is difficult to find two different inputs that produce the same hash
Avalanche effect: A small change in input results in a completely different hash value

Algorithm Descriptions

MD5 (128-bit) — Fast but no longer secure; suitable for file integrity checks
SHA1 (160-bit) — Proven vulnerable to collision attacks
SHA224/256 (224/256-bit) — SHA-2 family, high security, widely used
SHA384/512 (384/512-bit) — SHA-2 family, higher security
SHA3-256/512 (256/512-bit) — SHA-3 latest standard, highest security
AES-256-CBC — Symmetric encryption with key and IV for encrypting/decrypting data
HMAC — Keyed-hash message authentication code
Bcrypt — Password hashing algorithm with built-in salt and adjustable cost
CRC32 — Cyclic redundancy check for data integrity (not cryptographically secure)

Privacy Notice

All encryption and hashing computations are performed in your browser — no data is uploaded to any server. This tool uses CryptoJS to execute all calculations on the client side, so you can safely process sensitive data. AES encryption keys and IVs are only kept in the current page's memory and are cleared upon refresh.

Usage Scenarios

Password storage — Hash passwords using SHA256 or Bcrypt
File integrity verification — Compare MD5/SHA256 hashes after downloading
API signing — Use HMAC for request signature verification
Data encryption — Use AES to encrypt sensitive data for transmission
Data deduplication — Quickly check for duplicate data using hash values
