how to retrieve private key from .pfx file?

[Schoolar]

X509Certificate can retrieve public key from .cer file.
But how to retrieve private key from .pfx file?
Thanks!

Use open ssl or cert util tools to extract the private key from the pfx.

command in open ssl : pkcs12 -nocerts -in "Pfx file name &location"(e.g "C:\KarthikTest.pfx" -out "Strore location " (e.g "c:\KarthikPvatekey.key"


Thanks

If you want to extract private key from a pfx file and write it to PEM file
>>openssl.exe pkcs12 -in publicAndprivate.pfx -nocerts -out privateKey.pem
If you want to extract the certificate file (the signed public key) from the pfx file
>>openssl.exe pkcs12 -in publicAndprivate.pfx -clcerts -nokeys -out publicCert.pem
To remove the password from the private key file.
>> openssl.exe rsa -in privateKey.pem -out private.pem
This is required as, at the time of exporting privateKey, you have added a password to the private key to secure it. If you left the password with it, it will keep asking the password as any application tries to access it.
