Use the CSR Decoder to verify your Certificate Signing Request contains the correct information before submitting it to a Certificate Authority. Simply paste your CSR below.

SSL CSR Decode

Paste your CSR code below. Your CSR should start with -----BEGIN CERTIFICATE REQUEST----- and end with -----END CERTIFICATE REQUEST-----.

What Does the CSR Decoder Check?

The CSR Decoder decodes the encoded text in your Certificate Signing Request and displays the information it contains in a readable format. This lets you verify the details are correct before sending it to a Certificate Authority.

Common Name Verification

Confirm the domain name (CN) in your CSR exactly matches the domain you are applying the SSL certificate for.

Organization Details

Verify your organization name, unit, locality, state, and country code are correctly encoded in the CSR.

Key Size Check

See the RSA key size used in the CSR. A minimum of 2048 bits is required by all modern Certificate Authorities.

Contact Email

Review the contact email address embedded in the CSR, which the Certificate Authority may use for domain validation.
