Certificate Signing Request (CSR) Decoder

Input your CSR (PKCS#10 format):



This tool decodes a Certificate Signing Request (CSR) in Pkcs #10 format which is the most common format for CSRs. Like signed certificates, CSRs are also kept in base64.
Decoding a CSR allows you to read all the content of the owner that is kept in the signing request, like the distinguished name (DN), business or organization name, department or unit inside the organization, email address, city, region or state, country name, and the public key of the CSR.
When a certificate authority (CA) signs a certificate signing request, a signed certificate is created. The signed certificate will include all the information of the subject (the info from the CSR) and the information of the issuer (the CA), along with the public key from the CSR and the signature of the CA.
