Cryptography tools that are clear, fast, and privacy-first

Use focused crypto utilities for hashing, encoding, random generation, and learning when each primitive is appropriate. The first tools in this section are designed to run locally in the browser whenever possible.

Production-Ready Crypto Tools

SHA-256 Hash Generator

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

Generate MD5 hashes for legacy checksums and learn why MD5 should not be used for security-sensitive work.

Base64 Encode and Decode

Encode and decode Base64 text in your browser, with clear notes about what Base64 is and is not.

Secure Random Password Generator

Generate strong random passwords in your browser using cryptographically secure random values.

Secure Random Hex Generator

Generate cryptographically secure random hexadecimal strings in your browser for tokens, test data, and identifiers.

File Hash Generator

Generate SHA-256 hashes for local files in your browser without uploading file contents.

Guides And References

Hash Algorithm Comparison

Compare MD5, SHA-1, SHA-256, SHA-512, BLAKE2, and BLAKE3 by security status and practical use case.

Privacy And Limitations

Browser-only tools in this section process input on your device. Static pages are readable without account creation or server-side execution.

  • Hashing is not encryption and cannot be reversed to recover the original input.
  • Browser cryptography depends on a modern browser and a secure context for the strongest guarantees.
  • Educational pages explain practical use cases, but they are not a substitute for a security review of production systems.

FAQ

Do these crypto tools upload my data?

The initial crypto tools are designed to run in the browser. Hashing, Base64 conversion, and random generation can happen locally without sending your input to a server.

Are hashes encryption?

No. Hashes are one-way fingerprints for data integrity and comparison. Encryption is reversible with a key; hashing is not.

Which crypto page should I start with?

Use SHA-256 for integrity checks, Base64 for text-safe encoding, random password for account credentials, and random hex for token-like values.

Are these tools suitable for compliance-critical systems?

These pages are practical references and browser tools, not compliance guarantees. Regulated or high-risk systems still require architecture review and policy controls.

What are the limits of browser-only cryptography pages?

Browser tools are excellent for local processing and education, but they do not replace backend key management, access controls, and audited security workflows.
