>From the rsa(1) manpage:
openssl rsa [-inform PEM|NET|DER] [-outform PEM|NET|DER] [-in filename]
[-passin arg] [-out filename] [-passout arg] [-sgckey] [-des] [-des3]
[-idea] [-text] [-noout] [-modulus] [-check] [-pubin] [-pubout]
[-engine id]
So, OpenSSL supports one of three formats "PEM" (default), "NET" and "DER".
Try each one and see if any work.
KEY=/some/file/name.ext
for form in PEM NET DER
do
openssl rsa -inform $form -pubin -in $KEY -noout -text 2>&1 |
grep modulus: >/dev/null && echo "$form public key"
openssl rsa -inform $form -in $KEY -noout -text 2>&1 |
grep modulus: >/dev/null && echo "$form private key"
done
When I run this on a PEM formatted private key file I get:
PEM private key
