안드로이드에서 String의 SHA-3-512를 어떻게 계산합니까?

Android 애플리케이션에서 비밀번호 SHA-3-512를 원격 데이터베이스에 전송해야합니다. 내가 어떻게 할 수 있니?안드로이드에서 String의 SHA-3-512를 어떻게 계산합니까?

SHA-0/SHA-1/SHA-2/SHA-3의 차이점에 대해서는 잘 모르겠지만 사용 가능한 서비스 목록이 장치에 따라 다르므로 장치의 사용 가능한 서비스를 쿼리 할 수 있습니다.

MessageDigest digest = null; 
    try { 
     digest = MessageDigest.getInstance("SHA512"); 
     String password = "password"; 
     byte[] output = digest.digest(password.getBytes("UTF-8")); 
    } catch (NoSuchAlgorithmException e) { 
     e.printStackTrace(); 
    } catch (UnsupportedEncodingException e) { 
     e.printStackTrace(); 
    }

getInstance() 함수는 서비스 목록을 검사합니다. 내 롤리팝 장치에 그것은이다 : 대상 장치가 적절한 서비스가없는 경우

0 = "Provider AndroidOpenSSL Service MessageDigest.SHA-512 com.android.org.conscrypt.OpenSSLMessageDigestJDK$SHA512\nAliases [SHA512, 2.16.840.1.101.3.4.2.3] {}" 
1 = "Provider BC Service MessageDigest.SHA-512 com.android.org.bouncycastle.jcajce.provider.digest.SHA512$Digest\nAliases [SHA512, 2.16.840.1.101.3.4.2.3] {}"

것은, 당신이 Keccak을 포함해야합니다

는 당신이이 경기를 반환합니다 SHA512 지정하는 경우 구현 (SHA-3)을 코드 기반에 추가하십시오. 이러한 접근 방식은 모든 장치에서 확실히 작동하지만 심각한 보안 문제를 일으키는 오류가 발생하기 쉽습니다. 보안에 중대한 코드는 직접 구현/업데이트하지 말고 이미 사용 및 테스트 된 솔루션/라이브러리에 의존해야합니다.

SHA-3은 SHA512와 다릅니다. SHA-3 서비스를 사용하는 서비스를 찾지 못했습니다. 거대한 오류를 내지 않으면 서 Keccak 구현을 구현할 수 없기 때문에 다른 알고리즘이나 다른 솔루션을 시도 할 것이라고 생각합니다. 도움에 감사드립니다! –

[this] (https://github.com/diogovieira/jca-sha3-provider/blob/master/src/com/uminho/Keccak.java) 구현을 시도해 보셨습니까? JNI를 통해 [this] (https://github.com/gvanas/KeccakCodePackage/blob/master/Standalone/CompactFIPS202/Keccak-readable-and-compact.c)와 같은 C++ 구현이 가능합니까? – Habib
