SSL on the HP ProCurve switches supports these data encryption methods:
3DES (168-bit, 112 Effective)
DES (56-bit)
RC4 (40-bit, 128-bit)
Note: HP ProCurve switches use RSA public key algorithms and Diffie-Hellman. 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 certifi-
cate. Certificates on Procurve switches conform to the X.509v3 stan-
dard, which defines the format of the certificate.
