Generate SHA-256 hash for password verification
Create MD5 checksum for file integrity
Generate SHA-512 hash for API authentication
SHA-256 hash for data verification
Use SHA-256 for general security, MD5 for checksums only, and SHA-512 for maximum security requirements.
Compare hash values to ensure data hasn't been modified during transmission or storage.
MD5 and SHA-1 are considered weak for security purposes. Use SHA-256 or SHA-512 for sensitive applications.
For password storage, use salted hashes and consider using specialized password hashing functions like bcrypt.
Enter the text or data you want to hash
Choose from MD5, SHA-1, SHA-256, or SHA-512
Cryptographic function processes your input
Copy or download your generated hash value
Store password hashes instead of plain text passwords for security. Always use salt for password hashing.
Verify file integrity by comparing hash values before and after transmission or storage.
Create unique fingerprints for documents and data to detect any unauthorized changes.
Generate hash-based signatures for secure API authentication and request verification.
A cryptographic hash function takes input data of any size and produces a fixed-size string of characters. The same input always produces the same hash, but even small changes create completely different hashes.
For security applications, use SHA-256 or SHA-512. MD5 and SHA-1 are considered weak and should only be used for non-security purposes like checksums.
No, cryptographic hash functions are one-way. You cannot reverse a hash to get the original input. However, weak hashes like MD5 can sometimes be cracked using rainbow tables.
Yes, all hashing is performed locally in your browser. No data is sent to our servers, ensuring your input remains private and secure.
MD5 produces 128-bit hashes, SHA-1 produces 160-bit, SHA-256 produces 256-bit, and SHA-512 produces 512-bit hashes. Longer hashes are generally more secure.
