What is MD5 / SHA Hash?
Generate cryptographic hash values using MD5, SHA-1, SHA-256, and SHA-512 algorithms. Hash functions create unique fingerprints of data for integrity verification, password storage, and digital signatures.
Key Features
How to Use MD5 / SHA Hash
Enter text or upload a file
Select hash algorithm
Click Submit to generate
Copy the hash value
Common Use Cases
Tips & Best Practices
Use SHA-256 for security-sensitive applications
MD5 is fine for file checksums but not for passwords
Compare hash values to verify file downloads haven't been tampered with
Frequently Asked Questions
Which algorithm should I use?
SHA-256 for most purposes. MD5 and SHA-1 are considered weak for security but fine for checksums. SHA-512 for maximum security.
Can I reverse a hash?
No — hash functions are one-way. You cannot recover the original data from a hash value.
