Security
Tools
Generate hashes, verify checksums, create unique IDs — 100% private, running entirely in your browser.
Hash Generator
Generate MD5, SHA-1, SHA-256, SHA-512 cryptographic hashes for text and files. Essential for password hashing and data verification.
File Checksum Verifier
Verify file integrity with SHA-256, SHA-512 checksums. Compare downloads against official hashes to detect tampering.
UUID Generator
Generate UUID v1, v4, v5 identifiers. Bulk generation up to 1000 at once. Built-in validator for UUID verification.
Base64 Encoder/Decoder
Encode text to Base64 for safe transmission or decode Base64 strings. Full UTF-8 support for international characters.
Password Generator
Create strong, random passwords with customizable length and character sets. Generate cryptographically secure passwords locally.
Client-Side Only
All cryptographic operations happen in your browser. Nothing is sent to our servers—ever.
Industry Standards
Uses Web Crypto API with SHA-256, SHA-512, and other FIPS-approved algorithms.
Trusted by Developers
Perfect for verifying downloads, generating secure tokens, and file integrity checks.
Why Use Security Tools?
Verify Software Downloads
When downloading software, ISOs, or packages, publishers provide SHA-256 checksums. Use our File Checksum Verifier to confirm your download is authentic and hasn't been tampered with.
Generate Secure Identifiers
- •UUIDs: Create unique IDs for databases, APIs, and distributed systems
- •Hashes: Generate password hashes or verify data integrity
- •Base64: Encode tokens for HTTP headers and API authentication
Privacy-First Design
Unlike online hash generators that upload your data to servers, Filemint processes everything locally. Perfect for sensitive data, corporate environments, and compliance requirements where data must not leave your device.
Backup Integrity
Keep records of file checksums when creating backups. Periodically verify that backup files haven't degraded or been corrupted over time. Catch problems before you need to restore from backup.
