Microsoft "certutil -encode..." - Converte DER file to PEM

Q

How to convert a certificate file in DER (Distinguished Encoding Rules) format to PEM (Privacy Enhanced Mail) format? I know that PEM file format uses printable characters only and is safe to be included emails.

If you want to convert a certificate from DER format to PEM format, you can use the Microsoft "certutil -encode input_file output_file" command as shown in this tutorial: 

C:\fyicenter>\windows\system32\certutil -encode FYIcenter.crt FYIcenter.pem
Input Length = 530
Output Length = 788
CertUtil: -encode command completed successfully.

C:\fyicenter>type FYIcenter.pem
