In this section:
The Public Key Infrastructure (PKI) provides a common set of infrastructure features supporting public key and certificate-based authentication based on the RSA public/private key pairs and X.509 digital certificates. In previous The Certificate file format: PEM Local certificates are credentials belonging to the local system itself, which it presents to peers in order to prove its identity. You must download local certificate files to the system before installing the certificates. Certificate file format: PKCS12 Remote certificates are credentials belonging to Certificate Authorities (CA). The copies of these certificates are installed in the The Certificate Authority (CA) certificates and trusted remote certificates contain public key certificates; they do not contain the private keys. The CA certificates and remote certificates are Distinguished Encoding Rules (DER) format files; a method for encoding a data object (such as an X.509 certificate) which uses a digital signature to bind together a public key with an identity. Certificate file format: DERCertificate Types
Local-Internal Certificates
Unable to show "metadata-from": No such page "_space_variables" versions, the RSA key pairs and Certificate Signing Request (CSR) for Unable to show "metadata-from": No such page "_space_variables" platforms were generated on an external workstation. The CSR was then submitted to a Certificate Authority, and the resulting certificate was received back from the CA, copied onto the workstation, and combined with the private key in a PKCS#12 file which was used to install the key pair and certificate onto the Unable to show "metadata-from": No such page "_space_variables".Unable to show "metadata-from": No such page "_space_variables" application can now generate and install RSA key pairs and generate Certificate Signing Request (CSR) on the Unable to show "metadata-from": No such page "_space_variables" system itself. The certificate request is sent to a CA, and the issued certificate is then installed on the Unable to show "metadata-from": No such page "_space_variables". The local-internal certificate option simplifies the certificates and keys managing process and also provides more security since the private key never leaves the Unable to show "metadata-from": No such page "_space_variables". For steps to configure local-internal certificates, see Generating PKI Certificates.Local Certificates
Remote Certificates
Unable to show "metadata-from": No such page "_space_variables" because they are part of a chain of certificates the local system will present to peers, or because the corresponding CAs are trust anchors for the local system. Certificates belonging to non-CA remote systems should also be installed as trust anchors in this manner.
Note
The SBC supports a maximum of 4,096 TLS certificates/CAs (both local and remote).
The SBC allows importing of a single certificate in a single file only. If a CA provides a .p12 or a .pfx certificate bundle with multiple CA certificates in it, extract the certificates from the bundle, store them in separate files, and import them separately.

Request Parameters
request system security Parameters Parameter Description deleteUserPrivateKey – Delete an existing user-submitted private key. When the key is removed the SBC will revert back to using its default private key. generateDefaultKeys – Requests the generation of a new default SBC-generated private key pair. setUserPrivateKey <uniqueUserPrivateKeyName> <userPrivateKey> – Configures the user-submitted private key. The private key is encrypted in CDB using existing CDB encryption methods. The user-submitted private key is only available internally. The key is encrypted and hidden, thus not displayable, once configured in CDB. showPublicKey <user/default> – Access the public key associated with the chosen private key. Use this command to generate header encryption keys. A "Success" or "Failure" indication is returned. The SBC then adds the key-Id to each encrypted header based on which key is selected as the correct key for decryption. The SBC stores up to two sets of keys at any given time. There is no limit to the number of times this command may be executed. Additionally, there is no specific time delay required before reissuing the command. NOTE: Generating new keys too frequently may lead to a situation where the SBC receives a request with an expired key-id (i.e. the current header encryption key is over-written due to the new key generation) causing unsuccessful decryption of headers. This may lead to call failures any calls caught in the transition to the new key-id. PKI certification configuration details.
