Decoder for CSR
Decode your Certificate Signing Request with the help of this CSR Decoder, then check to be sure it contains all of the appropriate information. A Certificate Signing Request is a block of encoded data that includes information about the firm to which an SSL certificate will be granted as well as the SSL public key.
This information is included in the request for the certificate. Because the information in a CSR is encoded, once it has been created it is difficult to verify what information is contained within it. You are required to decode CSRs in order to ensure that the information contained within them is correct.
This is because certificate authorities use the information contained inside CSRs to create certificates. Simply copy and paste your CSR into the box below, and our CSR Decoder will do the rest of the work to check your CSRs and display the information that is encoded in them. Your CSR should begin with "——-BEGIN CERTIFICATE REQUEST——- " and end with "——-END CERTIFICATE REQUEST——- ".
Both of these phrases should be capitalized. You can also find out more information about Certificate Signing Requests if you are interested in doing so. Use our SSL Wizard to locate the most reliable SSL provider after you have obtained your CSR.
Execute the following command in OpenSSL on your personal computer if you want to check CSRs.
uses the following command: openssl req -in mycsr.csr -noout -text
The private key that corresponds to the public key contained in a CSR is used to sign a CSR document. By doing this check, you can ensure that the signature on the CSR is legitimate. A signature that is invalid suggests that the CSR has been altered after it was initially generated, or that the public key contained inside the CSR does not correspond to the private key that was used to sign it.
This check determines whether or not the name of the CSR contains a field that has no value. For instance, the CSR Decoder would provide a warning regarding the name that is provided below due to the fact that the location field is available, but it does not have a value.
CN=www.acme.com, O=acme, L=, and C=gb respectively.
This warning is necessary because some certification authorities (CAs) have the ability to reject CSRs that contain fields with empty values.
Performs tests to determine whether weak RSA keys were created by systems based on Debian.
It makes use of the dowkd blacklist, which may or may not be comprehensive.
This page contains CSRs and certificates that use keys that are already known to be weak. In the event that it fails to identify a CSR or certificate that you are aware to have a weak key, kindly inform us.
In May of 2008, the Debian team made the announcement that Luciano Bello had found a vulnerability in the OpenSSL package that was distributed by Debian. The result of this was that any SSL and SSH keys that were created on Debian-based systems (including Ubuntu) between September 2006 and May 13th, 2008 were potentially vulnerable to being compromised.
This flaw was discovered and reported by the Debian Security Team in the Debian Security Advisory number 1571. The Debian Wiki is the greatest source of information regarding this vulnerability. Additionally, this topic is covered in our CSR Frequently Asked Questions article.
Verifies that RSA and DSA keys have a minimum of 2048 bits, and that EC keys have a minimum of 224 bits

When it comes to the process of obtaining an SSL certificate issued, one of the papers that is considered to be of the utmost importance is a Certificate Signing Request, or CSR. When you generate a CSR, you are expected to provide information that may be checked for accuracy and completeness.
During the validation process, the Certificate Authority will check the information against what is contained in the CSR, and the information that is provided in the CSR is what populates the SSL certificate that is ultimately issued.
Unfortunately, it is sometimes very simple to confuse CSRs with one another. The most typical occurrence is found in huge enterprise-level operations that are maintaining dozens or even hundreds of certificates, as well as when you're using an old CSR to renew your SSL certificate. The second most common occurrence is when you're using an old CSR to renew your certificate. If you send the incorrect CSR, you are going to waste a lot of time. Fortunately, we are able to assist you.
The information that is contained in your Certificate Signing Request (CSR) is decrypted by the tool known as the Certificate Signing Request (CSR) Decoder so that you can check that it is accurate and up to date.
If you are renewing, it is likely that a certain detail in your CSR is either no longer applicable or has been updated. Before you send the CSR to your CA, it is essential that you construct a new one with up-to-date information, as this is the situation at hand.
The following should come first in your Certificate Signing Request:
——-START THE REQUEST FOR THE CERTIFICATE——-
...and finish with:
——- THIS BRINGS AN END TO THE CERTIFICATE REQUEST ——-
Please take note that both of the prompts should have five dashes on either side of them.
A word of advice from the community: If you want to reuse an older CSR to renew your SSL certificate, you should verify all of the information that is included in that CSR before you do so. When information is incorrect, both time and the labor of employees are squandered.
As is customary, if you have any inquiries or issues, please do not hesitate to contact one of our helpful SSL specialists by phone or using the live chat feature on our website. Our customer service is available around the clock, in English.
