These +extensions are denoted by individual bits in the capability vector. +When libcrypto is initialized, the bits returned by the STFLE instruction +and by the QUERY functions are stored in the vector. + +The OPENSSL_s390xcap environment variable can be set before starting an +application to affect capability detection. It is specified by a +colon-separated list of 64-bit values in hexadecimal notation, the 0x +prefix being optional. The ~ prefix means bitwise NOT and a point +indicates the end of the STFLE bits respectively the beginning of the +QUERY bits. + +After initialization, the capability vector is ANDed bitwise with the +corresponding parts of the environment variable. + +The following bits are significant: + +: +: + +=over + +=item #62 vector facility + +=back + +. + +=over + +=item #60 KIMD-SHA-512 + +=item #61 KIMD-SHA-256 + +=item #62 KIMD-SHA-1 + +=back + +: + +=over + +=item #62 KIMD-GHASH + +=back + +: + +=over + +=item #11 KM-XTS-AES-256 + +=item #13 KM-XTS-AES-128 + +=item #43 KM-AES-256 + +=item #44 KM-AES-192 + +=item #45 KM-AES-128 + +=back + +: +: + +=over + +=item #43 KMC-AES-256 + +=item #44 KMC-AES-192 + +=item #45 KMC-AES-128 + +=back + +: +: + +=over + +=item #43 KMAC-AES-256 + +=item #44 KMAC-AES-192 + +=item #45 KMAC-AES-128 + +=back + +: +: +: +: + +=over + +=item #43 KMO-AES-256 + +=item #44 KMO-AES-192 + +=item #45 KMO-AES-128 + +=back + +: +: + +=over + +=item #43 KMF-AES-256 + +=item #44 KMF-AES-192 + +=item #45 KMF-AES-128 + +=back + +: +: + +=over + +=item #60 PRNO-SHA-512-DRNG + +=back + +: + +=over + +=item #13 PRNO-TRNG + +=back + +: + +=over + +=item #43 KMA-GCM-AES-256 + +=item #44 KMA-GCM-AES-192 + +=item #45 KMA-GCM-AES-128 + +=back + +=head1 EXAMPLES + +OPENSSL_s390xcap=0:0:~0x4000000000000000 disables the vector facility. + +OPENSSL_s390xcap=.0:0 disables KIMD. + +OPENSSL_s390xcap=.::~0x2800 disables KM-XTS-AES. + +=head1 COPYRIGHT + +Copyright 2017 The OpenSSL Project Authors.
