aTalk supports XEP-0234: Jingle File Transfer. During jingle file transfer protocol, it requires a ‘Hash’ element to be defined. However when execute the function call below in JingleFile class (algorithm = HashManager.ALGORITHM.SHA3_256), the system throws java.security.NoSuchAlgorithmException: SHA3-256 MessageDigest not available. It happend in both sending and receiving jinglefile.
HashManager.getMessageDigest(algorithm)
This problem only happens in aTalk ported to use smack4.5.0-beta9. The problem does not happen in smack-4.4.8; this holds true even after aTalk build.gradle is updated to match the one for smack-4.5.0-beta9 e.g.
a. sourceCompatibility JavaVersion.VERSION_11
b. minSdkVersion 26
I am still not sure why this happen, as the above function is calling the same android-sdk (api-36) library i.e. java.security.MessageDigest class. I am unable to trace beyond that point.
Any help is much appreciated.
MessageDigest.getInstance("SHA3-384"); the exception happens at statement
@ Security.getImpl(algorithm, "MessageDigest", (String)null)
//=================
public static MessageDigest getInstance(String algorithm)
throws NoSuchAlgorithmException {
Objects.requireNonNull(algorithm, "null algorithm name");
try {
MessageDigest md;
Object[] objs = Security.getImpl(algorithm, "MessageDigest", (String)null);
if (objs[0] instanceof MessageDigest) {
md = (MessageDigest)objs[0];
} else {
md = new Delegate((MessageDigestSpi)objs[0], algorithm);
}
md.provider = (Provider)objs[1];
// Android-removed: this debugging mechanism is not used in Android.
/*
if (!skipDebug && pdebug != null) {
pdebug.println("MessageDigest." + algorithm +
" algorithm from: " + md.provider.getName());
}
*/
return md;
} catch(NoSuchProviderException e) {
throw new NoSuchAlgorithmException(algorithm + " not found");
}
}
Following is the aTalk logcat:
