About MD5 Hash

MD5 (Message Digest Algorithm 5) is a widely used cryptographic hash function that produces a 128-bit (16-byte) hash value. It is commonly used to verify data integrity.

Key characteristics:

Produces a 32-character hexadecimal number
Fixed-length output regardless of input size
One-way function (cannot be reversed)
Not suitable for password hashing (use bcrypt or Argon2 instead)

Common Examples

Empty String

MD5: d41d8cd98f00b204e9800998ecf8427e

"Hello, World!"

MD5: 65a8e27d8879283831b664bd8b7f0ad4

"password"

MD5: 5f4dcc3b5aa765d61d8327deb882cf99

Common Uses

Data Integrity

Verifying file integrity by comparing MD5 hashes before and after transfer

Digital Signatures

Creating digital signatures for documents and messages

Checksums

Generating checksums for error detection in data transmission

Security Considerations

Vulnerabilities

MD5 is considered cryptographically broken and unsuitable for further use due to collision vulnerabilities

Alternatives

For password hashing: bcrypt, Argon2, scrypt

For general hashing: SHA-256, SHA-3

Best Practices

Use stronger algorithms for security-critical applications

Always salt passwords before hashing

Consider using key stretching for password hashing
