[Docsis-users] extract a certificate from a modem

[Stanislav S. <ssi...@ya...>]

here's the promised script. It extracts the modem's individual
certificate. For vendor CVC, take a different OID


snmpget -OvQ -v2c -c public 172.34.34.254 \
DOCS-BPI2-MIB::docsBpi2CmDeviceCmCert.2 | \
perl -e '$/ = undef; $a=<STDIN>; $a =~ s/^0-9A-F//g; print pack("H*", $a)' | \
openssl x509 -inform DER -text >modem.cert
