    v1 v2  
    55org.bouncycastle.crypto.DataLengthException: input too large for RSA cipher.
    66}}}
    7 I am still a bit puzzled as to why pycrypto manages to decrypt such blocks and BouncyCastle does not. Either we fix the data length using a specific padding scheme (as the length of the input looks fine as it is: <100bytes with 4096bit keys is ok), or we use a symmetric cipher for all encrypted packets (and exchange it during the login phase).
