OpenSSL "req -verify" - Verify Signature of CSR
Q
How to verify the digital signature inside a CSR using OpenSSL "req -verify" command?
✍: FYIcenter.com
A
If you want to verify the digital signature inside a CSR (Certificate Signing Request),
you can use the OpenSSL "req -verify" command as shown below:
C:\Users\fyicenter>\local\openssl\openssl.exe OpenSSL> req -in my_rsa.csr -noout -verify verify OK
Options used in this "req" command are:
- "-in my_rsa.csr" - Read the CSR from the given file.
- "-noout" - Do not include CSR itself in the output.
- "-verify" - Verify the digital signature inside the CSR.
The output "verify OK" indicates that the decrypted digital signature matches the digest of the CSR data,
