readmbn /path/to/file.mbn
You can extract the code, signature, or X509 segments of the mbn file with:
$ readmbn /path/to/file.mbn -e code -o code.bin
$ readmbn /path/to/file.mbn -e signature -o signature.hash
$ readmbn /path/to/file.mbn -e x509 -o x509.der
Of course, le standard help with
$ readmbn --help
X509 certificates are in DER format and can be parsed with OpenSSL
openssl x509 -in x509.der -inform der -text -noout
