# Verifying Hashes and Signatures

Along with our releases, we also provide sha512 hashes in *.sha512 files and cryptographic signatures in *.asc files. The Apache Software Foundation has an extensive tutorial to verify hashes and signatures (opens new window) which you can follow by using any of these release-signing KEYS (opens new window) .
