icainfo-cex - print information about cryptographic functions supported by libica-cex
icainfo-cex [-v | --version] [-h | --help] [-c | --list-curves]
icainfo-cex prints a table that shows libica-cex's support for various cryptographic algorithms and information about FIPS support.
The icainfo-cex output also indicates, whether it is in an error state. Algorithms that are not FIPS approved are marked as blocked in both table columns when running in FIPS mode. All algorithms are marked as blocked when libica is in an error state.
Available hardware support is divided into two columns: dynamic hardware means crypto cards, static hardware support means CPACF. Software support is provided via openssl.
If a function is disabled via build option, this is indicated by a dash '-' in the related column.
A shortened sample output is given below:
Cryptographic algorithm support ------------------------------------------------------
| hardware |
function | dynamic | static | software ---------------+------------+------------+------------
SHA-1 | no | - | -
SHA-224 | no | - | -
SHA-256 | no | - | -
SHA-384 | no | - | -
SHA-512 | no | - | -
GHASH | no | - | -
P_RNG | blocked | - | -
DRBG-SHA-512 | no | - | -
RSA ME | yes | - | -
RSA CRT | yes | - | -
... ------------------------------------------------------ Built-in FIPS support: FIPS mode active. Software fallbacks are disabled in libica-cex. CPACF support (including fallbacks) is disabled in libica-cex.
