MD5 Hash
Generate 128-bit MD5 hash from text
About MD5 Hash
MD5 (Message Digest Algorithm 5) produces a 128-bit (32 hexadecimal characters) hash value. While fast and widely supported, MD5 is no longer considered cryptographically secure due to vulnerability to collision attacks.
Output length: 32 characters (128 bits)
Use cases: File integrity checks, non-cryptographic applications, legacy systems
Security note: Not recommended for password hashing or security-critical applications
Hash Properties
Deterministic: Same input always produces same output
Fixed Length: Output size is always constant
One-way: Cannot reverse hash to get original input
Avalanche Effect: Small input change = big hash change
Fast Computation: Quick to calculate
Collision Resistant: Hard to find two inputs with same hash
Security Notice
- • Hashes are not encryption - they cannot be reversed
- • For password storage, use proper password hashing functions (bcrypt, scrypt, Argon2)
- • Always use salt when hashing passwords or sensitive data
- • MD5 and SHA-1 are not recommended for security-critical applications
- • All processing is done locally - no data is sent to our servers
