Java Language에서 구현 한 Blowfish 암호화 알고리즘의 전체 코드 공유

며칠 전, 소문이 갑자기 인터넷에 나타났습니다. 특정 동쪽에서 12G의 데이터 유출이 발생했으며 결국 나는 성명서에서 그것을 거부하지 않았으며, 거의 인정되지 않았습니다. 이 문제가 평범한 사람들에게 어떤 영향을 미치는지, 어떻게 해야하는지에 대해 이미 많은 사람들이 있으므로 재미에 참여하지 않을 것입니다. 개인적으로 현재 비교적 안전하다고 생각하는 실용적인 암호화 알고리즘에 대해 이야기 해 봅시다 : Blowfish.

코드를 입력하기 전에 Blowfish 암호화 알고리즘의 특성에 대해 이야기하겠습니다.

1. 대칭 암호화, 즉 암호화 된 키와 해독 된 키는 동일합니다.
2. 각 암호화 후의 결과는 다릅니다 (이것은 내가 더 감사하는 것입니다).
3. 이전 기사에서 소개 된 MD5와 같은 추상 알고리즘과는 다른 가역적 인 경우 가역적입니다.
4. 빠른 속도, 암호화 및 암호 해독 공정은 기본적으로 ADD 및 XOR 명령 연산으로 구성됩니다.
5. 무료, 누구나 저작권 비용을 지불하지 않고 무료로 사용할 수 있습니다.
6. Blowfish는 한 번에 8 바이트의 데이터를 암호화하고 해독 할 수 있습니다.

Blowfish 알고리즘은 대칭 패킷 암호화 알고리즘입니다. 알고리즘의 핵심은 변수 길이 키를 총 길이 4168Byte의 서브 키 어레이로 확장하는 서브 키스 생성에 있습니다. 많은 수의 하위 키가 알고리즘에 사용되며 하위 키는 사용자 키에 의존합니다. 실제 첨가/암호 해독 프로세스에서 업데이트 된 서브 키 어레이, 즉 P 배열 및 S 상자가 사용됩니다. Blowfish 알고리즘에는 핵심 암호화 기능이 있습니다 : bf_en (). 이 기능의 입력은 64 비트 일반 텍스트 정보입니다. 계산 후 64 비트 암호 텍스트 정보 형식으로 출력됩니다. Blowfish 알고리즘을 사용하여 정보를 암호화하려면 주요 전처리 및 정보 암호화의 두 가지 프로세스가 필요합니다. 마찬가지로, 암호 해독은 또한 주요 전처리 및 정보 암호 해독의 두 가지 프로세스가 필요합니다.

Blowfish 알고리즘 -Pbox 및 Sbox의 소스 키가 수정되었습니다. 메시지를 암호화하려면 키를 선택 하고이 키를 사용하여 Pbox 및 Sbox를 변환하여 Key_pbox 및 key_sbox를 다음 정보 암호화 단계에 사용할 수 있도록해야합니다. 암호 해독도 마찬가지입니다. Blowfish는 대칭 암호화 알고리즘이므로 암호 해독 당사자는 키를 얻은 후 키를 기반으로 암호 해독에 필요한 key_box 및 key_sbox를 생성합니다. 동일한 정보를 암호화하고 해독하면 선택한 다른 키는 다른 암호화로 이어집니다. 따라서 Blowfish 알고리즘의 핵심은 키와 기밀성의 선택에 있습니다.

Blowfish 알고리즘은 가변 길이 키를 사용하기 때문에 사용자에게 편의성을 높일뿐만 아니라 숨겨진 위험도 있습니다. 알고리즘 암호화/암호 해독의 핵심은 키의 선택 및 기밀성에있어 실제 응용 분야에서 일부 약한 키는 종종 정보 자원을 암호화하는 데 사용되므로 보안 위험이 크게 높아집니다.

다음은 Blowfish 암호화 알고리즘의 구현 인 가장 중요한 부분입니다.

 패키지 cn.bridgeli.encrypt; public enum blowfishmanager {bridgeli_cn ( "bridgeli_cn!@#$ abc123_"); Private BlowfishManager (String Secret) {this.blowfish = New Blowfish (Secret); } 개인 블로우 피쉬 블로우 피쉬; 공개 블로우 피쉬 getblowfish () {return blowfish; } / ** * decrypt * @param sciphertext * @return * / public string decryptstring (String sciphertext) {return this.getBlowfish (). decryptstring (sciphertext); } / ** * encrypt * @param splaintext * @return * / public string encryptstring (String splaintext) {return this.getBlowfish (). EncryptString (splaintext); } public static void main (String [] args) {String EncrypTstring = blowfishmanager.bridgeli_cn.encryptstring (10 + ""); System.out.println (EncryptString); 문자열 decryptstring = blowfishmanager.bridgeli_cn.decryptstring (encryptstring); System.out.println (decryptstring); }}

이것은 외부 인터페이스로 사용하기가 매우 간단하며 사용자 친화적입니다. 다음은 알고리즘의 특정 구현입니다.
