따라서, 답변은 다음과 같습니다.
mcrypt_generic_init 함수의 매개 변수 key_size와 iv_size는 암호화 키와 초기화 벡터의 크기를 지정하는 데 사용됩니다.
key_size는 암호화 키의 크기를 바이트 단위로 지정합니다. 예를 들어, AES-128 암호화 키의 크기는 16바이트입니다. mcrypt 라이브러리는 다양한 암호화 알고리즘을 지원하므로, 각 알고리즘의 키 크기는 다음과 같습니다.
- DES: 8바이트
- 3DES: 24바이트
- CAST-128: 16바이트
- CAST-256: 32바이트
- IDEA: 16바이트
- IDEA2: 16바이트
- IDEA4: 32바이트
- IDEA8: 64바이트
