What are Security & Privacy?
Security tools on SabTools.in generate and test credentials without ever sending them to a server. Password generators, strength testers, hash calculators (MD5, SHA-1, SHA-256, SHA-512), UUID generators, base64 encoders — everything runs in your browser using the Web Crypto API. That matters because a password generator that sends your password to its server is not a security tool; it is a credential leak waiting to happen. Every security tool here is auditable in your browser's DevTools Network tab — you will see no outgoing request with the generated value.
Key Features & Capabilities
Web Crypto API generation
Password Generator uses crypto.getRandomValues() — the same cryptographically secure random number generator used by browsers for TLS. Unlike Math.random(), its output is unpredictable and suitable for credentials.
No-upload guarantee
Hash calculators, encoders, and password testers all process your input locally. You can disconnect from the internet after loading the page and every tool still works, which is proof that nothing is phoned home.
Compliance-friendly output
Password Generator respects common corporate rules — length 12-32, mandatory uppercase/lowercase/digit/symbol, no ambiguous characters (0/O/I/l/1) for systems with manual entry.
Modern crypto standards
Hash calculator includes MD5 (legacy) and SHA-1 (legacy) for compatibility with older systems, plus SHA-256, SHA-384, SHA-512, and SHA-3 variants for modern use. Encoder tools cover base64, URL encoding, and HTML entity encoding.
Common Use Cases
Generating a unique password for each account
The right way to use the internet is with a different strong password per account, stored in a password manager. Use the Password Generator to create a 20-character mix for each new signup, then paste it into your password manager. The Strength Tester grades your existing passwords so you know which ones to rotate first.
Verifying downloaded file integrity
Official Linux ISOs, Aadhaar card downloads from UIDAI, and signed PDFs from the Income Tax portal often publish SHA-256 hashes alongside the file. Drag the file into the Hash Calculator — if the hash matches the one on the official page, your download was not tampered with. If it does not, do not open the file.
Backend and DevOps work
UUID Generator produces v4 and v7 UUIDs for database IDs, the Base64 Encoder helps debug tokens in API requests, and the JWT Decoder inspects JSON Web Tokens (decode only — it does not validate signatures, so never trust JWTs just because they decode cleanly).
Teaching and learning cryptography
For students and curious learners, watching the same input produce identical hashes across runs, and watching a single-bit change produce a completely different hash (the avalanche effect), is the fastest way to build intuition for why hash-based integrity works.
How to Choose the Right Tool
For creating a new credential — Password Generator or Passphrase Generator (for human-memorable passwords). For testing an existing credential — Password Strength Tester. For file integrity — Hash Calculator (SHA-256 unless the source publishes a different algorithm). For encoding binary safely in text — Base64 Encoder. For generating database IDs — UUID Generator. For decoding tokens for debugging — JWT Decoder or Base64 Decoder. Each tool has a specific purpose and should not be substituted — do not use a hash as a password, do not use base64 as encryption, do not trust a JWT just because it parsed.
Security & Privacy Built for India
Indian digital services increasingly require strong credentials — banking apps enforce 8-16 character passwords with complexity rules, Aadhaar-linked services require OTP plus password, and corporate VPN and email rules often mandate 12+ characters with quarterly rotation. The Password Generator supports all these profiles with one-click presets (SBI, HDFC, ICICI typical rules; common CorpSec rules). For citizens dealing with DigiLocker, UMANG, and income-tax portal downloads, the Hash Calculator is the fastest way to verify the integrity of downloaded documents before opening them — match the published SHA-256 against the file you received, and the Indian Computer Emergency Response Team (CERT-In) recommends this exact step before opening any government-issued PDF. Our Privacy Policy Generator helps Indian SMEs draft DPDP Act 2023-compliant privacy policies — the Ministry of Electronics and Information Technology (MeitY) administers the act and non-compliance penalties are now serious.
