Cisco ASA Series Firewall CLI Configuration Guide
Chapter 16 Configuring the Cisco Phone Proxy
Troubleshooting the Phone Proxy
The SAST keys can be seen via the show crypto key mypubkey rsa command. The SAST keys are
associated with a trustpoint that is labeled _internal_ctl-file_name_SAST_X where ctl-file-name is the
name of the CTL file instance that was configured, and X is an integer from 0 to N-1 where N is the
number of SASTs configured for the CTL file (the default is 2).
Step 1 On the ASA, export all the SAST keys in PKCS-12 format by using the crypto ca export command:
hostname(config)# crypto ca export _internal_ctl-file_name_SAST_X pkcs12 passphrase
hostname(config)# Exported pkcs12 follows:
MIIGZwIBAzCCBiEGCSqGSIb3DQEHAaCCBhIEggYOMIIGCjCCBgYGCSqGSIb3DQEH
[snip]
MIIGZwIBAzCCBiEGCSqGSIb3DQEHAaCCBhIEggYOMIIGCjCCBgYGCSqGSIb3DQEH
---End - This line not part of the pkcs12---
hostname(config)# crypto ca export _internal_ctl-file_name_SAST_X pkcs12 passphrase
hostname(config)# Exported pkcs12 follows:
MIIGZwIBAzCCBiEGCSqGSIb3DQEHAaCCBhIEggYOMIIGCjCCBgYGCSqGSIb3DQEH
[snip]
mGF/hfDDNAICBAA=
---End - This line not part of the pkcs12---
hostname(config)#
Note Save this output somewhere secure.
Step 2 Import the SAST keys to a new ASA.
a. To import the SAST key, enter the following command:
hostname(config)# crypto ca import trustpoint pkcs12 passphrase
Where trustpoint is _internal_ctl-file_name_SAST_X and ctl-file-name is the name of the CTL file
instance that was configured, and X is an integer from 0 to 4 depending on what you exported from
the ASA.
b. Using the PKCS-12 output you saved in Step 1, enter the following command and paste the output
when prompted:
hostname(config)# crypto ca import _internal_ctl-file_name_SAST_X pkcs12 passphrase
hostname(config)# Enter the base 64 encoded pkcs12.
hostname(config)# End with the word "quit" on a line by itself:
MIIGZwIBAzCCBiEGCSqGSIb3DQEHAaCCBhIEggYOMIIGCjCCBgYGCSqGSIb3DQEH
