RSA Keypair Generator

This tool leverages the Web Crypto API, a modern browser standard for cryptographic operations, to generate RSA keypairs directly in your browser. When you select a key size (2048, 3072, or 4096 bits) and initiate generation, the cryptographic computation happens entirely on your local machine. No data is transmitted to external servers, ensuring complete privacy and security.

Once generated, your keypair consists of a public key and a private key. The tool allows you to export both keys in PEM (Privacy Enhanced Mail) format, which is the universally recognized standard for storing and sharing cryptographic keys. PEM format is compatible with virtually all programming languages, frameworks, and cryptographic tools, making it ideal for integration into your projects.

The higher the bit length you choose, the stronger your encryption—4096-bit keys offer maximum security for long-term protection, while 2048-bit keys are suitable for most contemporary applications. The generation process is fast and resource-efficient, even for higher bit lengths.

• SSH Key Generation: Create RSA keypairs for secure shell (SSH) authentication on servers and version control platforms like GitHub
• SSL/TLS Certificate Requests: Generate keypairs as the foundation for creating self-signed certificates or CSRs (Certificate Signing Requests)
• API Authentication: Generate keypairs for OAuth, JWT, or other token-based authentication mechanisms in web applications
• Data Encryption & Signing: Create keypairs for encrypting sensitive data, digitally signing documents, and verifying authenticity
• Development & Testing: Quickly generate test keypairs for local development environments without installing additional cryptographic software
