Compute SHA-1, SHA-224, SHA-256, SHA-384, SHA-512, SHA-3, and RIPEMD-160 hashes, generate HMACs, and encrypt/decrypt text with AES. All client-side, no server uploads.
Compute MD5, SHA-1, SHA-256, and SHA-512 hashes from text or file input using CryptoJS.
JWT tools (decode, encode/sign HS256, validate expiry/signature), OAuth tools (client setup, PKCE generator/verifier, scope builder, state/token validator), crypto tools (bcrypt PBKDF2, AES-128-CBC encrypt/decrypt, cookie parser/security analyzer, CSP nonce generator/policy builder), SSL scanner, and SAML assertion decoder. (SHA/MD5 hash has its own dedicated page.)
Generate RSA key pairs (2048/4096-bit) using the Web Crypto API. Export public and private keys as PEM strings. All client-side, no server uploads.
Counts characters with and without spaces and compares your text against platform-specific limits — Twitter/X posts (280), SMS messages (160), SEO meta descriptions (160), Facebook posts (63,206), and LinkedIn summaries (2,600). Real-time counting with space/no-space toggle.
Cloud tools (AWS IAM policy analyzer), converters (JSON to YAML, Excel to CSV), CIDR calculator, and extras (hash generator SHA-1/256/384/512, Markdown quick editor with live preview). (Password strength checker has its own dedicated page.)
Crypto & Hash Toolkit lets you compute SHA-1, SHA-224, SHA-256, SHA-384, SHA-512, SHA-3, and RIPEMD-160 hashes, generate HMACs, and encrypt/decrypt text with AES. All client-side, no server uploads.. Everything runs inside your browser — nothing is uploaded to a server. It works on any device with a modern web browser.
Compute SHA-1, SHA-224, SHA-256, SHA-384, SHA-512, SHA-3, and RIPEMD-160 hashes, generate HMACs, and encrypt/decrypt text with AES. All client-side, no server uploads. It's ideal for developers, designers, and anyone who needs to compute sha-1, sha-224, sha-256, sha-384, sha-512, sha-3, and ripemd-160 hashes, generate hmacs, and encrypt/decrypt text with aes without installing software or sending data to external servers.
Direct text entry, file upload, or URL-based input — depending on the tool. Paste or type your content directly into the provided editor area.
Yes. After the initial page load, Crypto & Hash Toolkit runs entirely on your device with no internet connection needed. All processing is done locally.
Tools cover JavaScript, CSS, HTML, SQL, Python, JSON, XML, CSV, and more. Check individual tool descriptions for specifics.
No. All code processing — formatting, minification, conversion, hashing — runs locally in your browser.
Yes. Since processing is local, performance depends on your device. Most operations handle large files without issue.
Yes. SQL uses sql-formatter, JSON uses native JSON.parse, and other formatters follow widely adopted formatting rules.
Yes. All developer tools work fully offline after the initial page load.
Time Converter
Convert between time units including seconds, minutes, hours, days, weeks, months, and years with precise decimal results.
Diff Checker
Compares two input texts side-by-side, highlighting inserted, deleted, and changed lines with distinct background colors.
Regex Tester
Provides an interactive environment where users can write a regular expression pattern, test it against sample strings, and view real-time match.
JSON Formatter
Pretty-prints raw JSON with configurable indent width, key sorting, and bracket collapsing options while flagging syntax errors with exact.
JS Minifier
Strips comments, whitespace, and shortens local variable names in JavaScript source without altering execution semantics.
Base64 Encode/Decode
Encodes text or small files into Base64 strings and decodes them back with automatic MIME-type detection for binary safety.
