Converting Files
Converting PFX to KEY File
openssl pkcs12 -in yourfile.pfx -clcerts -nokeys -out certificate.crt
Enter Import Password:ENTER_PASSWORD
MAC verified OK
openssl pkcs12 -in yourfile.pfx -nocerts -out certificate-tmp.key
Enter Import Password:ENTER_PASSWORD
MAC verified OK
Enter PEM pass phrase: tegsoft123
Verifying - Enter PEM pass phrase: tegsoft123
openssl rsa -in certificate-tmp.key -out certificate.key
Enter passphrase for certificate-tmp.key: tegsoft123
writing RSA key
Converting CRT to PFX File
openssl pkcs12 -export -out certificate.pfx -inkey certificate.key -in certificate.crt -certfile bundle.crt
Converting KEY to 8 Bit KEY File
openssl pkcs8 -topk8 -inform PEM -outform DER -in certificate.key -nocrypt > certificate8.key
Converting CER to PEM File
openssl x509 -inform der -in certificate.cer -out certificate.pem
Converting CRT to PEM File
openssl x509 -in certificate.crt -out certificate.pem -outform PEM
Certificate Verification
Certificate Verification
openssl verify -verbose certificate.crt
Key Verification
openssl rsa -noout -modulus -in certificate.key | openssl md5
Key - Certificate Matching
openssl pkey -in certificate.key -pubout -outform pem | sha256sum
openssl x509 -in certificate.crt -pubkey -noout -outform pem | sha256sum
openssl x509 -in certificate.crt -text -noout
