4. SOPS加密实践：使用SOPS加密YAML/JSON/ENV文件、加密特定字段、使用age加密
SOPS（Secrets OPerationS）是Mozilla开源的加密工具，专为云原生环境设计。它支持对YAML、JSON、ENV等配置文件进行结构化加密，允许仅加密文件中的敏感字段（如密码、），而非整个文件。本节将演示如何使用SOPS配合age密钥进行加密实践。
4.1 环境准备与age密钥生成
age是一个现代、安全的文件加密工具，SOPS原生支持age作为加密后端。首先需要生成age密钥对：
# 生成age密钥对
age-keygen -o agekey.txt
# 查看公钥
cat agekey.txt | grep "# public key:"
# 输出示例: # public key:
