For details, see Installing the KAE Software Using an RPM Package in the KAE Developer Guide (KAE Encryption & Decryption).

Download the RPM package (version 1.3.11). CentOS 7.6 is used as an example.

cd /home/
wget https://gitee.com/kunpengcompute/KAE/releases/download/v1.2.10/kae_1.3.11_CentOS.7.6.4.14.0-115.el7a.0.1.zip --no-check-certificate

Decompress the package.

unzip kae_1.3.11_CentOS.7.6.4.14.0-115.el7a.0.1.zip
ll -rt

Go to the directory generated after decompression.

cd 'kae_1.3.11_CentOS 7.6 4.14.0-115.el7a.0.1'
ll -rt

Install the RPM package of uacce.

rpm -ivh uacce-1.3.11-1.centos7.6.aarch64.rpm

Install the RPM package of hisi_hpre.
