BcryptSHA512 Generator
Generate and verify bcrypt(sha512($pass)) hashes instantly with this free browser-based tool. Useful for legacy or high-security systems that require a SHA512→Bcrypt hashing scheme.
What is BCRYPTSHA512?
BcryptSHA512 is a two-step hashing approach where a password is first hashed using the SHA512 algorithm, producing a 512-bit digest, which is then hashed using bcrypt. This method is sometimes used for systems requiring both a strong hash (SHA512) and adaptive key stretching (bcrypt). While bcrypt remains secure, applying SHA512 first is mostly useful for compatibility with specific applications rather than as a necessity for new systems.

FAQ
Is this bcryptsha512 generator free?
Yes. This bcryptsha512 tool runs entirely in your browser with no installation or server required.
Why combine SHA512 and bcrypt?
Some systems use SHA512 before bcrypt for legacy compatibility or to produce a larger digest before bcrypt. This adds an extra layer for specific security requirements.
Can I use this to verify a bcryptsha512 hash?
Yes. Paste a hash and its original password into the verifier to instantly check if they match.
Which bcrypt formats are supported?
This tool supports bcrypt(sha512($pass)) in common bcrypt variants, including $2a$, $2b$, and $2y$.
Is bcryptsha512 recommended for new applications?
No. While SHA512 is strong, for new systems it’s usually sufficient to use bcrypt directly or more modern algorithms like Argon2. SHA512 before bcrypt is primarily for compatibility or legacy use.
