This patch adds support for Chinese cryptographic algorithms in the IPsec security gateway example application:
1 Add SM4-CBC cipher algorithm support with 16-byte IV and key; 2 Add SM3-HMAC authentication algorithm support with 20-byte key; 3 Update SA configuration parsing to recognize "sm4-cbc" and "sm3-hmac" keywords; 4 Implement proper IV handling and authentication offset/length configuration. These additions enable the IPsec security gateway to use Chinese national cryptographic standards for secure communications.
