The bar mitzvah attack is an attack on the SSL/TLS protocols that exploits the use of the RC4 cipher with weak keys for that cipher. [1] [2] While this affects only the first hundred or so bytes of only the very small fraction of connections that happen to use weak keys, it allows significant compromise of user security, for example by allowing the interception of password information [2 ...
RC4 + is a modified version of RC4 with a more complex three-phase key schedule (taking about three times as long as RC4, or the same as RC4-drop512), and a more complex output function which performs four additional lookups in the S array for each byte output, taking approximately 1.7 times as long as basic RC4. [62] All arithmetic modulo 256.
iText is a library for creating and manipulating PDF files in Java and . NET.It was created in 2000 and written by Bruno Lowagie. The source code was initially distributed as open source under the Mozilla Public License or the GNU Library General Public License open source licenses.
The attack exploits the fact that many [2] regular expression implementations have super-linear worst-case complexity; on certain regex-input pairs, the time taken can grow polynomially or exponentially in relation to the input size. An attacker can thus cause a program to spend substantial time by providing a specially crafted regular ...

The basis of the FMS attack lies in the use of weak initialization vectors (IVs) used with RC4. RC4 encrypts one byte at a time with a keystream output from prga(); RC4 uses the key to initialize a state machine via ksa(), and then continuously modifies the state and generates a new byte of the keystream from the new state.
