1、下载源码包

wget https://www.php.net/distributions/php-7.4.20.tar.gz

2、安装必要工具软件依赖

sudo apt install -y build-essential gcc libcurl3-dev pkg-config libxml2-dev libssl-dev sqlite3 libsqlite3-dev libbz2-dev libgmp3-dev libonig-dev libedit-dev libreadline-dev libxslt1-dev autoconf postgresql

3、解压,配置

tar xvf php-7.4.20.tar.gz
cd php-7.4.20/
./configure --prefix=/usr/local/php74 --with-config-file-path=/usr/local/php74/ini_path --with-config-file-scan-dir=/usr/local/php74/config_path   --enable-mysqlnd   --with-pdo-mysql   --with-pdo-mysql=mysqlnd   --enable-bcmath   --enable-fpm   --with-fpm-user=www-data   --with-fpm-group=www-data   --enable-mbstring   --enable-phpdbg   --enable-shmop   --enable-sockets   --enable-sysvmsg   --enable-sysvsem   --enable-sysvshm   --with-zlib   --with-curl   --with-pear   --with-openssl   --enable-pcntl   --with-readline

make -j8 && make install

4、运行

/usr/local/php74/bin/php -v

高级加密标准(英语:Advanced Encryption Standard,缩写:AES),又称Rijndael加密法,是美国联邦政府采用的一种区块加密标准。这个标准用来替代原先的DES,已经被多方分析且广为全世界所使用。经过五年的甄选流程,高级加密标准由美国国家标准与技术研究院(NIST)于2001年11月26日发布于FIPS PUB 197,并在2002年5月26日成为有效的标准。现在,高级加密标准已然成为对称密钥加密中最流行的算法之一。
aes-192密钥的长度为24字节,aes-256密钥的长度为32字节,aes-128密码的长度为16字节。aes-ccm需要key,nonce,adata,另外aes-ccm不需要填充。

高级加密标准(英语:Advanced Encryption Standard,缩写:AES),又称Rijndael加密法,是美国联邦政府采用的一种区块加密标准。这个标准用来替代原先的DES,已经被多方分析且广为全世界所使用。经过五年的甄选流程,高级加密标准由美国国家标准与技术研究院(NIST)于2001年11月26日发布于FIPS PUB 197,并在2002年5月26日成为有效的标准。现在,高级加密标准已然成为对称密钥加密中最流行的算法之一。
aes-192密钥的长度为24字节,aes-256密钥的长度为32字节,aes-128密码的长度为16字节。aes-ccm需要key,nonce,adata,另外aes-ccm不需要填充。

aes-192密钥的长度为24字节,aes-256密钥的长度为32字节,aes-128密码的长度为16字节。aes-ccm需要key,nonce,adata,另外aes-gcm不需要填充。
GCM ( Galois/Counter Mode) 指的是该对称加密采用Counter模式,并带有GMAC消息认证码。
