在Ubuntu上使用OpenSSL主要涉及安装、配置以及执行各种加密任务。以下是一个详细的教程,帮助你了解如何在Ubuntu系统上使用OpenSSL。
sudo apt update
sudo apt install openssl libssl-dev
sudo apt update
sudo apt install build-essential checkinstall zlib1g-dev
wget https://www.openssl.org/source/openssl-1.1.1u.tar.gz
tar -xvf openssl-1.1.1u.tar.gz
cd openssl-1.1.1u
./config --prefix=/usr/local/openssl shared zlib
make -j$(nproc)
sudo make install
echo 'export PATH="/usr/local/openssl/bin:$PATH"' >> ~/.bashrc
echo 'export LD_LIBRARY_PATH="/usr/local/openssl/lib:$LD_LIBRARY_PATH"' >> ~/.bashrc
source ~/.bashrc
openssl genrsa -out private.key 2048
openssl req -new -key private.key -out certificate.csr
openssl x509 -req -days 365 -in certificate.csr -signkey private.key -out certificate.pem
openssl enc -aes-256-cbc -salt -in inputfile -out encryptedfile
openssl dgst -md5 inputfile
openssl passwd -crypt password
openssl rand -base64 32
openssl genrsa -out privatekey.pem 2048
openssl rsa -in privatekey.pem -pubout -out publickey.pem
openssl x509 -in certificate.pem -text -noout
openssl enc -aes-256-cbc -salt -in plaintext.txt -out encrypted.bin -pass pass:yourpassword
openssl enc -d -aes-256-cbc -in encrypted.bin -out decrypted.txt -pass pass:yourpassword
openssl dhparam -out dhparams.pem 2048
openssl ecparam -name secp384r1 -genkey -noout -out ecdh_key.pem
openssl dgst -sha256 -sign private_key.pem -out signature.bin data.txt
openssl dgst -sha256 -verify public_key.pem -signature signature.bin data.txt
openssl rand -base64 32
openssl rand -out random_file.bin 1024
openssl rsa -in rsa_key.pem -check -noout
openssl x509 -in certificate.pem -outform DER -out certificate.der
openssl x509 -in certificate.der -outform PEM -out certificate.pem
以上步骤和命令涵盖了在Ubuntu上安装和使用OpenSSL的基本操作。对于更高级的使用,如配置SSL/TLS服务器和客户端、管理证书颁发机构(CA)等,可以参考OpenSSL的官方文档或相关教程。
