Bcrypt Generator

Bcrypt is the gold standard for password hashing in modern applications. Unlike simple cryptographic hashes like MD5 or SHA-1, bcrypt is intentionally computationally expensive—it gets slower as computers get faster—making it extraordinarily resistant to brute-force password guessing. This tool lets you إنشاء bcrypt hashes and verify passwords against them, all without transmitting your passwords over the network.

Why bcrypt beats simple hashing

If you simply hash a password with SHA-256 and store the hash, an attacker with that hash can try billions of password guesses per second using modern GPUs. Bcrypt solves this by incorporating a configurable "cost factor" (salt rounds) that makes each hash computation take significant time. Even with a cost factor of 10, each hash takes about 100 milliseconds—meaning an attacker could only try 10 passwords per second instead of billions.

Salt rounds matter

This tool lets you choose between 10 and 13 salt rounds. Cost 10 is suitable for most web applications and completes in roughly 100ms per hash. Cost 12 or 13 is recommended for high-security applications like financial systems, though hashing will take longer (seconds instead of milliseconds). As computers get faster, you can increase the cost factor to keep hashing slow.

Hashing and verification

Enter any password and the tool إنشاءs a bcrypt hash. Unlike reversible تشفيرion, bcrypt hashing is one-way—you cannot decrypt the hash back to the original password. To verify a password, bcrypt takes the original password, applies the same algorithm, and compares the result against the stored hash. This tool includes a verification section where you can test whether a password matches a bcrypt hash.

Safe to share hashes

Bcrypt hashes are safe to store in databases and safe to share publicly. Even if an attacker has the hash, finding the original password through brute force would take centuries.
