Devify - The Next Generation Verifier!

Every major and/or secure file that's uploaded has a File Hash or Digital Signature along with it. The most common are;

• SHA256 Hashes: sha256.txt
• MD5 Hashes: md5.txt
• GPG Signatures: *.sig

What Devify aims to do is, verify the safety of your files with the SHA256 Hashing Algorithm.
