You can remove this self-signed certificate by disabling the secure HTTP server and entering the
no crypto
pki trustpoint TP-self-signed-30890755072 global configuration command. If you later re-enable a secure
HTTP server, a new self-signed certificate is generated.
The values that follow TP self-signed depend on the serial number of the device.
Note
You can use an optional command ( ip http secure-client-auth ) to allow the HTTPS server to request an
X.509v3 certificate from the client. Authenticating the client provides more security than server authentication
by itself.

Interoperability

chapter in the Cisco IOS Security Configuration Guide, Release 12.4 .
CipherSuites
A CipherSuite specifies the encryption algorithm and the digest algorithm to use on a SSL connection. When
connecting to the HTTPS server, the client Web browser offers a list of supported CipherSuites, and the client
and server negotiate the best encryption algorithm to use from those on the list that are supported by both.
For example, Netscape Communicator 4.76 supports U.S. security with RSA Public Key Cryptography, MD2,
MD5, RC2-CBC, RC4, DES-CBC, and DES-EDE3-CBC.
For the best possible encryption, you should use a client browser that supports 128-bit encryption, such as
Microsoft Internet Explorer Version 5.5 (or later) or Netscape Communicator Version 4.76 (or later). The
SSL_RSA_WITH_DES_CBC_SHA CipherSuite provides less security than the other CipherSuites, as it does
not offer 128-bit encryption.
The more secure and more complex CipherSuites require slightly more processing time. This list defines the
CipherSuites supported by the switch and ranks them from fastest to slowest in terms of router processing
load (speed):
1
SSL_RSA_WITH_DES_CBC_SHA
—
RSA key exchange (RSA Public Key Cryptography) with DES-CBC
for message encryption and SHA for message digest
2 SSL_RSA_WITH_NULL_SHA key exchange with NULL for message encryption and SHA for message
digest (only for SSL 3.0).
3 SSL_RSA_WITH_NULL_MD5 key exchange with NULL for message encryption and MD5 for message
digest (only for SSL 3.0).
