MD5 Generator
Generate MD5 hash values from text input. Useful for checksums, data integrity verification, and legacy applications.
Security Notice: MD5 is considered cryptographically broken and unsuitable for security applications. It should not be used for password storage, security tokens, or any application requiring collision resistance. Consider using SHA-256 or stronger algorithms for security-critical applications.

About MD5 Hashing
MD5 (Message Digest Algorithm 5) is a widely used cryptographic hash function that produces a 128-bit (16-byte) hash value, typically expressed as a 32-character hexadecimal number.
Key characteristics of MD5:
- Fixed output length of 128 bits (32 hexadecimal characters)
- Deterministic: the same input will always produce the same output
- Fast computation, even for large inputs
- Designed to be a one-way function (cannot easily derive the original input from the hash)
Security Limitations:
- MD5 is vulnerable to collision attacks (different inputs producing the same hash)
- It should not be used for password storage, digital signatures, or security certificates
- For security-critical applications, use SHA-256, SHA-3, or other modern hash functions
Common uses for MD5 today:
- File integrity checking (non-security critical)
- Checksums for data corruption detection
- Legacy systems where security is not the primary concern
- Quick data identification where collision resistance is not required
