Note that in default installations of the Java Runtime Environment, the maximum key length is limited to 128 bits due to US export restrictions. This makes the generated keys incompatible with the ones generated by pycryptopp, which has no such restrictions. To fix this, download the "Unlimited Strength Jurisdiction Policy Files" from Sun, which will allow encryption using 256 bit AES keys. i����( t Cipher( t SecretKeySpect IvParameterSpecNi t bc C sG t j d � } t | d � } | j t j | t � | j | � j � S( Ns AES/CTR/NoPaddingt AES( R t getInstanceR t initt ENCRYPT_MODEt _ivt doFinalt tostring( t datat keyt ciphert skeySpec( ( sH /opt/alt/python27/lib/python2.7/site-packages/beaker/crypto/jcecrypto.pyt aesEncrypt s c C s t j d � } t | d � d S( Ns AES/CTR/NoPaddingi i ( R t getMaxAllowedKeyLengtht min( t maxlen( ( sH /opt/alt/python27/lib/python2.7/site-packages/beaker/crypto/jcecrypto.pyt getKeyLength s ( t __doc__t javax.cryptoR t javax.crypto.specR R t jarrayt zerosR R t aesDecryptR ( ( ( sH /opt/alt/python27/lib/python2.7/site-packages/beaker/crypto/jcecrypto.pyt <module> s
