About this tool
Generate SHA-1, SHA-256, SHA-384 and SHA-512 hashes of any text. Hashes are fixed-length fingerprints often used to check data integrity.
Frequently asked questions
Can a hash be reversed?
No. Hashing is one-way.
Can I use SHA-256 to store passwords?
Plain SHA hashes are not suitable for passwords. Use a purpose-built algorithm such as bcrypt or Argon2.
