SHA-256 is a cryptographic hash function that produces a fixed 256-bit digest — rendered as 64 hexadecimal characters — from any input. It is the hash behind TLS certificates, Bitcoin block headers, Git object IDs, and most modern signing schemes. EasyRead computes SHA-256 locally with the browser's Web Crypto API, so sensitive inputs such as tokens or passphrases never leave your device.
Hash a file's contents or a release artifact and compare against a published checksum to detect tampering or corruption.
Generate SHA-256 digests of request bodies or canonical strings for HMAC-based auth schemes like AWS SigV4.
Use a SHA-256 digest of content as a cache key or deduplication ID when the original value is too large or sensitive to store.
Inspect or reproduce hashes used as object IDs in Git, Docker layers, and content-addressable stores.
Always 256 bits (32 bytes), printed as a 64-character lowercase hexadecimal string regardless of the input length.
No. SHA-256 is a one-way function. For passwords, pair it with a salt and a slow KDF such as bcrypt, scrypt, or Argon2.
Yes. MD5 and SHA-1 are broken for collision-resistance and should not be used for new security work. SHA-256 is the current baseline.
Yes. SHA-256 is deterministic — identical bytes in produce identical digests out, every time.
Yes. Hashing is delegated to window.crypto.subtle.digest, which runs in native code inside your browser.
