CSR Decoder: check your CSR before you submit it
A wrong letter in the common name means a reissue and a delay. Paste your CSR here and confirm every field before you activate your certificate.
Paste your CSR
Decoded in your browser. Nothing is uploaded.
Result
The decoded fields appear here: common name, SANs, organization, country, key size and signature algorithm.
My CSR shows a 1024-bit key. Is that a problem?
Yes. Certificate authorities reject keys under 2048 bits. Generate a new CSR with 2048 or 4096-bit RSA.
The organization field is empty. Can I still order?
For a DV certificate yes. For OV or EV certificates the organization name is required and must match your registered business name.
