NoSuchProviderException when encrypting string with 3DES

Question

I am new to Java. I followed this tutorial about Encryption and Decryption using 3DES algorithm.

I have implemented like this:

Created a class and placed the 3DES code provided in the above link.

Called the encrypt method in the above link as below:

String encryptedPassword = Encrypter.encrypt(edtText.getText().toString());

I am getting the exception in logcat as below:

Please help me. How to solve this....

Somewhere in your code you are specifying the SunJCE provider. That doesn't make any sense even where it would work, such as in Oracle's java runtime. Of course that provider doesn't exist on Android. Use the default provider unless you have a very good reason to do otherwise. — President James K. Polk, May 02 '13 at 23:02
@user2326860 Alter your code and remove anywhere where it explicitly states `"SunJCE"`. For example, change `("DESede/CBC/PKCS5Padding","SunJCE");` to `("DESede/CBC/PKCS5Padding");`. — Duncan Jones, May 03 '13 at 06:54

Sorry, I was being lazy. The line

Cipher ecipher = Cipher.getInstance("DESede/CBC/PKCS5Padding","SunJCE");

shows that you are specifying a particular provider. Normally you would want a very good reason for doing this, for example you might be required to use a FIPS-compliant provider. The SunJCE provider does not exist on Android. Just use the default provider, which you get simply by leaving out that argument. So try:

Cipher ecipher = Cipher.getInstance("DESede/CBC/PKCS5Padding");

Similarly, change

Cipher dcipher = Cipher.getInstance("DESede/CBC/PKCS5Padding","SunJCE");

to

Cipher dcipher = Cipher.getInstance("DESede/CBC/PKCS5Padding");
