     <h3>Why does bcrypt have a 72-character input limit?</h3>
     <p>The original bcrypt algorithm only processes the first 72 bytes of input. Passwords longer than 72 characters are silently truncated. For very long passwords, pre-hash with SHA-256 before bcrypt if needed.</p>

-
-      <h3 style="color:#00ff88;margin-top:20px;margin-bottom:8px;">What is Bcrypt?</h3>
-      <p>Bcrypt is an adaptive password hashing function based on the Blowfish cipher. Unlike MD5 or SHA-256, it is intentionally slow with a configurable cost factor (salt rounds), making brute-force and rainbow table attacks impractical. The cost factor controls the number of iterations as 2^cost — so each increment doubles the computation time. Cost factor 12 is the 2026 OWASP minimum recommendation; 13–14 is preferred for new systems where hardware budget allows.</p>
-
-      <h3 style="color:#00ff88;margin-top:20px;margin-bottom:8px;">Why Use a Client-Side Bcrypt Generator?</h3>
-      <p>Most online bcrypt tools send your password to a server, exposing it to logging, interception, or misuse. CipherKit runs entirely in the browser using the bcryptjs library — your password never leaves your device. This makes it ideal for developers testing password hashing, verifying bcrypt hashes against known values, or learning how the algorithm works without any privacy risk.</p>
-
-      <h3 style="color:#00ff88;margin-top:20px;margin-bottom:8px;">When Should You Use Bcrypt?</h3>
-      <p>Bcrypt is the right choice for password storage in databases — you should never store plaintext passwords. Use a bcrypt hash generator when building authentication systems, or when configuring a bcrypt password encoder such as Java Spring Security's <code>BCryptPasswordEncoder</code>. It's also essential when verifying bcrypt hashes during migration from weaker algorithms like MD5 or SHA-1. Developers working with node bcrypt or bcryptjs libraries can use this tool for bcrypt online testing before production implementation, validating outputs and cost factor timing without writing boilerplate code.</p>
