Hash & Encoder
Generate hashes and encode/decode text in various formats
💡 About Hash Functions
MD5: 128-bit hash, fast but not collision-resistant. Common for checksums.
SHA-1: 160-bit hash, deprecated for security but still used for integrity checks.
SHA-256: 256-bit hash, widely used in security applications and protocols.
SHA-512: 512-bit hash, strongest option with the longest output.
💡 About Base64
Base64 encoding represents binary data using 64 ASCII characters. Commonly used for embedding images in CSS/HTML, email attachments (MIME), and data URIs. It increases the data size by approximately 33%.
💡 About URL Encoding
URL encoding (percent-encoding) replaces unsafe characters with % followed by their hex value.
Required for special characters in URLs, query strings, and form data.
For example, a space becomes %20 and & becomes %26.
💡 About HTML Entities
HTML entities replace characters that have special meaning in HTML.
For example, < becomes < and & becomes &.
Essential for displaying code snippets and preventing XSS vulnerabilities.
