Hash passwords using SHA1 followed by bcrypt for secure and compatible outputs.
Supported Tools:
Generate and verify bcrypt(sha1($pass)) hashes instantly with this free browser-based tool. Useful for legacy systems that require a SHA1→Bcrypt hashing scheme.
It is a two-step hashing method where a password is first hashed using the SHA1 algorithm, and the resulting digest is then hashed with bcrypt. This approach is sometimes used in older systems for compatibility reasons. While bcrypt itself is secure and adaptive, SHA1 is considered weak against collision attacks. It is therefore primarily for maintaining compatibility with existing applications rather than for new deployments.
Input:
keydecryptor
Output:
$2b$10$o1pFzLZ4jq/lr9LQkIViwe9m9dSnz78ea43sZ9MxsydBx4uXWK1x.
Is this bcryptsha1 generator free?
Yes. This tool runs entirely in your browser with no installation or server required.
Why combine SHA1 and bcrypt?
Some legacy systems used SHA1 before bcrypt was widely adopted. To maintain compatibility, bcrypt is applied to the SHA1 hash of a password.
Can I use this to verify a bcryptsha1 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(sha1($pass)) in common bcrypt variants, including $2a$, $2b$, and $2y$.
Is bcryptsha1 recommended for new applications?
No. It is supported mainly for compatibility with older systems. For new projects, bcrypt (without SHA1) or Argon2 is recommended.
