[SNMP4J] HMAC-MD5 vs MD5

[Marco.Bresciani]

Which is the difference between HMAC-MD5 and MD5!?

Thanks,

Ing. Marco Bresciani

MD5 is just a hash function to calculate the Message digest.

Any iterative cryptographic hash function, such as SHA-1 and MD5, may be used in the calculation of an HMAC.
HMAC-MD5 means using MD5 hash function to calculate the Message digest WITH A SECRET KEY(normally attach the secret at the end of the message then MD5). If you use HMAC-MD5 to authenticate, the secret key is the shared key between client and server.

Hopefully this helps

Thank you,
very kind from you.

Another, maybe stupid, question... does SNMP4J support HMAC-MD5?!

Yes, if you use the USM model.
