  content.txt     ..... This file
  meddigo.h       ..... General header file for the Meddigo library
  texte_extract.c ..... Extracts encrypted data in MS Word and MS Excel document 
                        (up to Office 2003).
  detect.c        ..... Detects parallel (aka weak) ciphertexts in a ciphertext directory.
                        Weak ciphertexts can be produced by stream ciphers (pseudo-random generators
                        or Vernam systems) or by block ciphers in stream cipher mode.
  detect_singlefile.c   .... Detects when a single encrypted file has been encrypted by combination
                             with a cyclic short random sequence. This is interesting especially for
                             encrypted malware.

Corpus/           ..... Directory containing data to produce statistical models (aka corpus) from
                        plaintexts
  create_corpus.c ..... Program to create 4-grams corpus (4 is the optimal value)
  corpus.h        ..... The header file containing everything to manage corpus (hash table...)
  Texts/          ..... Subdirectory containing various texts to produce a corpus
  working_corpus  ..... Working corpus (4-grams over a 96-character alphabet)

Ciphertexts/      ..... Directory containing various ciphertexts to play with 
                        (detection step mainly; decryption left as exercice)
Ciphertexts2/     ..... Directory containing various ciphertexts to play with
                        (detection and decryption) 
Ciphertexts3/     ..... Directory containing various ciphertexts whose encryption
                        has been performed with a cyclic short sequence. 
                        Use defect_singlefile.c for detection

Decryption/       ..... Directory containing programs and data to decrypt parallel texts
  working_corpus  ..... Working corpus (4-grams over a 96-character alphabet)
  decrypt_para.c  ..... program to decrypt up to 5 parallel ciphertexts
  decipher.c      ..... Decipher an encypted text with the random sequence recovered
