Apps help: encryption/decryption in android

[vkrishna17]

I am writing an application which encrypts and decrypts the user notes based on the user set password. i used the following algorithms for encryption/decryption 1. PBEWithSHA256And256BitAES-CBC-BC 2. PBEWithMD5And128BitAES-CBC-OpenSSL
e_Cipher = Cipher.getInstance(PBEWithSHA256And256BitAES-CBC-BC);
d_Cipher = Cipher.getInstance(PBEWithSHA256And256BitAES-CBC-BC);
e_Cipher.init()
d_Cipher.init()
encryption is working well, but when trying to decrypt it gives

Exception - Illegal Block size
​

after encryption i am converting the cipherText to HEX and storing it in a sqlite database. i am retrieving correct values from the sqlite database during decyption but when calling d_Cipher.dofinal() it throws the Exception.

I thought i missed to specify the padding and tried to check what are the other available cipher algorithms but i was unable to found.
so request you to please give the some knowledge on
what are the cipher algorithms and padding that are supported by Android? if the algorithm which i used can be used for padding, how should i specify the padding mechanism?
I am pretty new to Encryption so tried a couple of algorithms which are available in BouncyCastle.java but unsuccessful.

Welcome to the forum!

Hey, it's only been a few hours. Your subject line is quite good, someone will no doubt get back to you "soon". In the meantime, try to be patient. I know it's difficult.

Incidentally, it's good policy to search for threads with zero responses, to look for questions that need answering. So, by adding your 2nd post to this thread, you've actually done yourself a disservice because your thread no longer shows up in 0-response searches. Now you know.

Good luck!
