CSR code (Certificate Signing Request) requires to apply for an SSL certificate. CSR is a message sent from an applicant to a certificate authority (CA). This is widely using in Secure Sockets Layer (SSL) registration, Transport Layer Security (TLS) activation and most of the modern servers. Only 2048-bit CSR Codes are allowed today; 1024-bit CSR codes are disallowed. You can generate CSR on your server OR in most cases you may use our Online CSR Generator. For IIS servers we suggest not to use any Online Generators and generate CSR on your servers only.
We provide the most popular and fast 2048-bit Free Online CSR Generator, which automatically generates CSR and RSA private key. Our system may send generated CSR/Key to email if you want.
