Generate MD5, SHA-1, SHA-256, SHA-384, SHA-512 hash values from text.
Enter the text you want to hash in the text area above.
Hash values for all algorithms (MD5, SHA-1, SHA-256, SHA-384, SHA-512) are automatically calculated as you type.

Hash Generator is an online tool that calculates cryptographic hash values from text. It supports five algorithms: MD5, SHA-1, SHA-256, SHA-384, and SHA-512, and can be used for data integrity verification and checksum calculation. Hash values for all algorithms are calculated in real-time as you type.
Vulnerabilities to collision attacks (generating the same hash from different inputs) have been discovered in MD5 and SHA-1. For security purposes (password hashing, digital signatures, etc.), use SHA-256 or higher. They can still be used for simple checksums or compatibility purposes.
It depends on the use case. For security purposes, SHA-256 or higher is recommended. SHA-256 is the most common for balancing performance and security. Use SHA-512 when higher security is required.
No, hash functions are deterministic. The same input always produces the same hash value. However, differences in whitespace, line breaks, or encoding can produce different results.
No, hash functions are one-way functions. It's impossible to compute the original text from a hash value. This is why hashing is used for storing passwords.
No, all processing happens entirely in your browser. Calculations are performed locally using the Web Crypto API, and your input data is never sent to any server.
