Cybersecurity & Privacy Tools

Generate strong, random passwords with custom length, complexity, and character options. Includes strength meter.

Generate MD5, SHA-1, SHA-256, and SHA-512 cryptographic hashes from any text input.

Encode text or files to Base64 and decode Base64 strings back to text or binary.

Decode and inspect JWT tokens — view header, payload, expiration, and claims without a private key.

Generate RFC-4122 UUID v4 identifiers — single or bulk generation with copy support.

Test regular expressions live with real-time match highlighting, capture groups, and flag options.

Encrypt and decrypt text using AES-256-GCM with a passphrase. All processing happens locally in your browser.

Upload a JPEG image to view EXIF metadata including GPS location, camera info, and timestamps. Runs locally.

Calculate network address, broadcast address, usable host range, and subnet mask from an IP and CIDR.

Percent-encode URLs for safe transmission or decode percent-encoded strings.

Generate random API keys and tokens with custom length, alphabet, and prefix.

Compute MD5, SHA-1, SHA-256, and SHA-512 checksums for any uploaded file without uploading to a server.

Remove all EXIF metadata from JPEG images before sharing. Download the cleaned image with no GPS or personal data.

Encode any text to hexadecimal representation or decode hex back to readable text.

Generate memorable, strong passphrases from a word list with separator and capitalization options.

Parse any CIDR notation to get a full subnet summary including IP range and available hosts.

Check if an image contains metadata that could expose your location, device, or identity before sharing.

Generate cryptographically secure random bytes, hex strings, or Base64 tokens using Web Crypto API.

Extract IPs, URLs, domains, email addresses, and hashes from text or log data automatically.

Convert text to binary (1s and 0s) encoding or decode binary back to readable text.

Generate HMAC signatures using SHA-1, SHA-256, or SHA-512 with a secret key.

Inspect PEM-encoded certificates, public keys, and CSRs — view type, subject, issuer, validity, and fingerprint.

View and remove metadata from PDF files — author, creator, title, subject, and creation dates.

Paste raw HTTP headers to identify security headers and get descriptive notes on each.

Automatically redact IPs, emails, tokens, API keys, JWTs, and secrets from log files.

Inspect PEM-encoded X.509 certificates: subject, issuer, validity dates, SANs, and fingerprint.

Encode special characters to HTML entities and decode HTML entities back to characters.

Generate Base32-encoded TOTP secrets compatible with authenticator apps like Google Authenticator.

View name, size, type, extension, and MIME type for any uploaded file without sending it to a server.

Generate HTTP Basic Authorization headers from username and password, or decode existing ones.

Parse user-agent strings to identify browser, OS, device type, and engine.

Extract IPs, URLs, and email addresses from large text blocks with deduplication support.

Mask emails, phone numbers, credit cards, tokens, and other sensitive data patterns in text.

Encode characters to Unicode escape sequences (\uXXXX) or decode them back.

Compare two hash strings to verify file integrity or detect tampering.

Inspect a file's magic bytes to detect its real type — regardless of the extension.

Parse raw HTTP cookie strings into structured key/value tables for easy inspection.

Parse and format Content Security Policy headers with directive grouping and unsafe value warnings.

Generate properly formatted DNS records (A, AAAA, CNAME, MX, TXT) from field inputs.

Decode and inspect PEM-encoded Certificate Signing Requests to view subject details and public key info.

Parse and inspect SSH public keys — view key type, bits, fingerprint, and algorithm details.

Paste YARA detection rules for syntax-friendly display with section highlighting and formatting.

Format and inspect Sigma detection rules with structured preview and validation-friendly display.
