Compute SHA-1, SHA-256, SHA-384, or SHA-512 hashes of text content using the Web Crypto API. Code never leaves your device — formatting and validation run locally in your browser.
Generate PBKDF2 hashes with 10,000 iterations of SHA-256 for password storage simulation. Tune iterations to hardware — slower hashes resist brute force — free, local, no signup.
Decode and inspect JWT tokens — view header, payload, expiration, issuer, subject, and other standard claims. Paste an HMAC secret to genuinely verify HS256/384/512 signatures — local inspection, free, no signup.
Compute test percentages and grades from correct/total with curve options. Turn 42/50 into 84% (B) instantly — free, local, no signup.
Compute simple probability as favorable outcomes divided by total outcomes — coin flips, dice rolls, card draws. See 3 in 10 read as 30.0% instantly — free, local, no signup.
MD5, SHA-1, SHA-256, and SHA-512. Each produces a fixed-length hash string — MD5 (32 hex chars), SHA-1 (40), SHA-256 (64), SHA-512 (128).
Yes. Paste text or upload a file. The tool computes the hash of the file contents using the CryptoJS library entirely in your browser.
MD5 is faster but cryptographically broken — vulnerable to collision attacks. SHA-256 is secure and recommended for password hashing, digital signatures, and data integrity checks.
No. This tool computes raw hashes. For password hashing, you should add a random salt before hashing and use a slow algorithm like bcrypt or Argon2 instead.
No. Hashing happens entirely in your browser using CryptoJS. Neither your text nor file contents are transmitted to any server.
Empty or whitespace-only input only toasts 'Please enter input text' - nothing computes. There are no salt, iteration, encoding or file-picker options in this tool: one button runs all 4 CryptoJS digests (MD5, SHA-1, SHA-256, SHA-512) over the textarea verbatim.
