About String to Hash Converter
A cryptographic hash function is a mathematical algorithm that maps data of arbitrary size to a bit array of a fixed size. It is a one-way function, meaning it is practically impossible to invert or reverse the process to get the original input.
Our free online Hash Converter allows you to generate hashes using popular algorithms like MD5, SHA-1, SHA-256, SHA-384, and SHA-512. Whether you are verifying file integrity, safely storing passwords, or checking digital signatures, our tool provides instant, secure, and client-side processing.

Frequently Asked Questions
Can I decrypt a hash back to the original text?
No, hashing is a one-way process. Unlike encryption, it cannot be reversed. To 'crack' a hash, one would typically have to guess the input (brute-force) or use a rainbow table.
Which hash algorithm should I use for passwords?
For password storage, modern standards recommend slow hashing algorithms like Argon2 or bcrypt. However, if you must use a general-purpose hash, SHA-256 or SHA-512 are significantly more secure than MD5 or SHA-1.
Why should I avoid MD5 and SHA-1?
MD5 and SHA-1 are considered cryptographically 'broken' because researchers have found ways to generate collisions (two different inputs producing the same hash) much faster than brute force. They should not be used for security-critical applications.
Cryptographic hashes are the backbone of modern digital security. Our tool simplifies the process of generating these checksums, helping developers and security enthusiasts ensure data integrity and authenticity with ease.
