The current default cipher suite list can be different from the install time list due to changes made to the QSSLCSL (SSL cipher specification list) system value via the Change System Value (CHGSYSVAL) command. A cipher suite removed from the SSL cipher specification list will also be removed from the default cipher suite list shown here. The order of the cipher suites in QSSLCSL will be used to order the cipher suites in the default list. 4. The Display System Value (DSPSYSVAL) command or the Retrieve System Values (QWCRSVAL) API can be used to determine the current setting of the supported ciphers (QSSLCSL) for system SSL. unsigned int cipherSuiteListLen (input) The number of cipher suite entries specified in the list pointed to by the cipherSuiteList parameter. Authorities Authorization of *R (allow access to the object) to the key database file and its associated files is required. Return Value The SSL_Init() API returns an integer. Possible values are: [0] Successful return [SSL_ERROR_BAD_CIPHER_SUITE] A cipher suite that is not valid was specified. [SSL_ERROR_IO] An error occurred in SSL processing; check the errno value. [SSL_ERROR_KEYPASSWORD_EXPIRED] The specified key ring password has expired. [SSL_ERROR_NO_KEYRING] No key ring file was specified. [SSL_ERROR_SSL_NOT_AVAILABLE] SSL is not available for use. [SSL_ERROR_UNSUPPORTED] Operation is not supported by SSL. None of the specified protocol or cipher values are supported by System SSL. [SSL_ERROR_UNKNOWN] An unknown or unexpected error occurred during SSL processing. 82 System i: Programming Secure Sockets APIs
Error Conditions When the SSL_Init() API fails with return code [SSL_ERROR_IO], errno can be set to: [EINVAL] [EACCES] Parameter not valid. Permission denied. This error code indicates one of the following: v The keyringFileName field contains a file name to which the user is not authorized. v The keyringPassword value is not valid for the specified keyringFileName. [EBADF] Descriptor not valid. This error code indicates one of the following: v The keyringFileName value does not specify a valid key ring file name. [EFAULT] [EUNATCH] Bad address. The system detected an address that was not valid while attempting to access the init parameter or one of the address fields in the init parameter. The protocol required to support the specified address family is not available at this time. [EUNKNOWN] Unknown system state. Error Messages Message ID Error Message Text CPE3418 E Possible APAR condition or hardware failure. CPF9872 E Program or service program &1 in library &2 ended. Reason code &3. CPFA081 E Unable to set return value or error code. Usage Notes 1. A successful SSL_Init(), QlgSSL_Init (using NLS-enabled path name), or an SSL_Init_Application() API must be used to enable a job for SSL processing before attempting to use any other SSL API. 2. If multiple SSL_Init_Application (), QlgSSL_Init, or SSL_Init() APIs are performed in a job, then only the values associated with the last SSL_Init_Application(), QlgSSL_Init, or or SSL_Init() performed are used. 3. If the keyringPassword parameter pointer value is equal to NULL, then SSL_Init() will attempt to extract the password value as stored on the system with the keyringFileName parameter’s value. The existence of the securely stored key database password is based on a configuration selection made during the creation of the key database file. 4. The Change System Value (CHGSYSVAL) command allows an administrator to disable protocols or ciphers from being used by the SSL_ APIs. For backwards compatibility, SSL_ support will silently Secure Sockets APIs 83
