CryptoTools

Cryptographic tools for your browser in a Single-Page app

This website crypto.francescogorini.com is a cryptographic playground to play with, test and learn about cryptography.
It runs all cryptographic operations in the browser utilising SubtleCrypto API, PKIJS and ASN1JS.

This project uses:

• React
• Typescript
• Material UI
• PKI.js
• ASN1.js

Roadmap

• RSA Key Generation.
• ECDSA Key Generation with NIST P-256 P-384 and P-521 curve support.
• PKCS10/CSR Generation with custom Subjects and with ECDSA, RSA-PSS and RSASSA-PKCS1-v1_5 signatures.
• PKCS10/CSR Generation with custom Subject Alternative Names.
• x509 Certificate Generation/Signing with custom key/cert.

Encrypt/Decrypt

• AES-CBC Encrypt/Decrypt.
• AES-GCM Encrypt/Decrypt.
• RSA-OAEP Encrypt/Decrypt.
• AES-GCM with additional authenticated data AEAD.
• File encryption support.
