Mac verify error: invalid password? Converting .p12 to .pem using openssl pkcs12

Question

I keep getting this error:

Mac verify error: invalid password?

For these two commands:

openssl pkcs12 -nocerts -out PushKey.pem -in moo.p12

openssl pkcs12 -nocerts -out PushKey.pem -in moo.p12 -nodes

moo.p12 is issued by apple for push notifications

Answer 1

You should have a password that come with the pfx file.

Try to put the password in the command line like this. Then you'll get both the private key and certificate in pem format:

openssl pkcs12 -nocerts -out PushKey.pem -in moo.p12 -nodes -password pass:<mypassword>

Answer 2

Note: as already said, you should have a password that come with the pfx file.

In case they have not shared with you any password, maybe the password is just an empty one. In this case, try with -passin pass: to express an empty password.

Example:

openssl pkcs12 -in input.p12 -out output.pem -nodes -passin pass:
