java - Cannot find any provider supporting AES/GCM/NoPadding -


we trying encryption supporting aes/gcm/nopadding in java 7 getting below exception.

cannot find provider supporting aes/gcm/nopadding

code sample generating cipher instance below.

secretkeyspec eks = new secretkeyspec(k, "aes"); cipher c = cipher.getinstance("aes/gcm/nopadding"); c.init(cipher.encrypt_mode, eks, new gcmparameterspec(128, iv));

this cipher not supported java 7 se (exception solaris).

public static void main(string[] args) throws exception {     (provider provider : security.getproviders()) {         (map.entry<object, object> entry : provider.entryset()) {             if (((string) entry.getvalue()).contains("gcm")) {                 system.out.printf("key: [%s]  value: [%s]%n",                     entry.getkey(),                     entry.getvalue());             }         }     } }

you might have @ bouncy castle service provider in case.

small snippet using bouncycastle.

  1. download bcprov-jdk15on-154.jar http://www.bouncycastle.org/latest_releases.html

  2. register service provider in code

    security.addprovider(new bouncycastleprovider());

  3. then able use cipher (the paramter "bc" specifies use bounce castle service provider, can omitted if there no other provider same cipher)

    cipher c = cipher.getinstance("aes/gcm/nopadding", "bc");

java 8 support cipher out of box with

cipher c = cipher.getinstance("aes/gcm/nopadding");

scala - 'wrong top statement declaration' when using slick in IntelliJ -

Image
i'm porting project scala 2.9 2.10, therefore have use slick instead of scalaquery. i'm using slick 2.1.0 since supports ms access. according this tutorial , upgrade guide changed robs object class , added val robs : why error message wrong top statement declaration , how rid of it? edit: i'm new scala... according this question seems can't put val outside of methods or classes, right? code above directly in packge. right approach slick then? should move code in class or trait? according this changed val robs = tablequery[robs] to object robs extends tablequery(new robs(_)) {} . no warnings or errors anymore. :)
