SSL/TLS CSR Decoder
The SSL/TLS CSR Decoder on T00LZ is a specialized utility for developers and system administrators who need to inspect Certificate Signing Requests before they are submitted to a Certificate Authority. A CSR is an encoded block of text that contains your public key and organizational details, and it's crucial to ensure that this information is 100% accurate to avoid costly errors during the SSL issuance process. Our tool allows you to instantly decode and verify the Common Name, Organization, and location details directly in your browser, ensuring that your web security setup is professional and error-free.
Local Decoding: This tool parses PEM encoded data directly in your browser using the node-forge library. Your certificates and CSRs are never transmitted to our servers, ensuring your security credentials remain private.
