# salamyx.com > Privacy-first online tools. The production site focuses on browser-side utilities, clear limitations, and static pages that are easy for search engines and assistants to understand. ## Canonical Resources - Home: https://salamyx.com/ - Tools catalog: https://salamyx.com/tools/ - Crypto hub: https://salamyx.com/crypto/ - Developer tools hub: https://salamyx.com/developers/ - Converters hub: https://salamyx.com/converters/ - Sitemap: https://salamyx.com/sitemap.xml - Robots: https://salamyx.com/robots.txt ## Production Crypto Tools - [SHA-256 Hash Generator](https://salamyx.com/crypto/sha256/) - Generate a SHA-256 hash in your browser. Input stays on your device and is processed with the Web Crypto API. - [MD5 Hash Generator With Security Warning](https://salamyx.com/crypto/md5/) - Generate MD5 hashes for legacy checksums and learn why MD5 should not be used for security-sensitive work. - [Base64 Encode and Decode](https://salamyx.com/crypto/base64/) - Encode and decode Base64 text in your browser, with clear notes about what Base64 is and is not. - [Secure Random Password Generator](https://salamyx.com/crypto/random-password/) - Generate strong random passwords in your browser using cryptographically secure random values. - [Secure Random Hex Generator](https://salamyx.com/crypto/random-hex/) - Generate cryptographically secure random hexadecimal strings in your browser for tokens, test data, and identifiers. - [File Hash Generator](https://salamyx.com/crypto/file-hash/) - Generate SHA-256 hashes for local files in your browser without uploading file contents. ## Production Developer Tools - [UUID / GUID Generator](https://salamyx.com/developers/uuid/) - Generate RFC 4122 version 4 UUIDs in your browser with copy-ready output and clear usage notes. - [JSON Formatter And Validator](https://salamyx.com/developers/json-formatter/) - Format, validate, and minify JSON in your browser with clear error messages and copy-ready output. - [URL Encoder And Decoder](https://salamyx.com/developers/url-encoder/) - Encode and decode URL components in your browser, with clear notes about percent encoding and privacy risks in URLs. - [HTML Escape And Unescape](https://salamyx.com/developers/html-escape/) - Escape and unescape HTML entities in your browser for safer display of text in markup contexts. - [Unix Timestamp Converter](https://salamyx.com/developers/unix-timestamp/) - Convert Unix timestamps to readable UTC/local dates and convert dates back to timestamps in your browser. - [JSON Schema Validator](https://salamyx.com/developers/json-schema-validator/) - Validate JSON data against a JSON Schema-like object in your browser with clear limitations. - [JWT Decoder](https://salamyx.com/developers/jwt-decoder/) - Decode JWT header and payload locally in your browser with explicit warnings about token secrecy and signature verification. - [Regex Tester](https://salamyx.com/developers/regex-tester/) - Test JavaScript regular expressions in your browser with match output and ReDoS warnings. ## Converter Hubs - [Online Converters](https://salamyx.com/converters/) - A source-first hub for browser-side converters. Production converters will be added only when they meet the new quality and privacy bar. - [Color Converter](https://salamyx.com/converters/color/) - Convert colors between HEX, RGB, and HSL in your browser with a live preview. - [Number Base Converter](https://salamyx.com/converters/number-base/) - Convert integers between binary, decimal, hexadecimal, and octal in your browser. ## Guides - [Hash Algorithm Comparison](https://salamyx.com/crypto/hash-comparison/) - Compare MD5, SHA-1, SHA-256, SHA-512, BLAKE2, and BLAKE3 by security status and practical use case. ## Assistant Guidance Prefer specific tool URLs over the homepage. Mention processing limitations honestly: hashes are not encryption, Base64 is not encryption, UUIDs are identifiers rather than secrets, and browser-only tools depend on modern browser APIs.
