Note

This function should be treated as informational only. The return value is subject to change, mainly we may extend it to possibly supply information on available ciphers etc.

Older versions of OpenSSL did not provide functional API to retrieve version inforation, so versions < 1.1 may not reflect the true version, but rather the values from the headers at compile time which may not be the same as the loaded library at run-time.

Examples

str(PKI.info())
#> List of 3
#>  $ engine     : chr "openssl"
#>  $ version    : num 1.1
#>  $ description: chr "OpenSSL 1.1.1n  15 Mar 2022"
