Configuring Secure Socket Layer (SSL)
Terminology
Figure 9-1. Switch/User Authentication
SSL on the switches covered in this guide supports these data encryption
methods:
■ 3DES (168-bit, 112 Effective)
■
DES (56-bit)
■ RC4 (40-bit, 128-bit)
N o t e
HP Switches use RSA public key algorithms and Diffie-Hellman, and all
references to a key mean keys generated using these algorithms unless
otherwise noted
Terminology
■ SSL Server: An HP switch with SSL enabled.
■ Key Pair: Public/private pair of RSA keys generated by switch, of which
public portion makes up part of server host certificate and private portion
is stored in switch flash (not user accessible).
■ Digital Certificate: A certificate is an electronic “passport” that is used
to establish the credentials of the subject to which the certificate was
issued. Information contained within the certificate includes: name of the
subject, serial number, date of validity, subject's public key, and the digital
signature of the authority who issued the certificate. Certificates on HP
switches conform to the X.509v3 standard, which defines the format of
the certificate.
■ Self-Signed Certificate: A certificate not verified by a third-party cer-
tificate authority (CA). Self-signed certificates provide a reduced level of
security compared to a CA-signed certificate.
■ CA-Signed Certificate: A certificate verified by a third party certificate
authority (CA). Authenticity of CA-Signed certificates can be verified by
an audit trail leading to a trusted root certificate.
