The plaintext output is compared to language models, and a list of probable languages is provided. The DECODER maps an uploaded and transcribed ciphertext and a key of your choice, and decodes the ciphertext given the key. CrypTool 2 provides a variety of cryptanalytical tools to analyze or break classical (as well as modern) ciphers and can be downloaded for Windows. Under development.ĬrypTool 2 (CT2) is an open-source, e-learning platform for cryptography and cryptanalysis, offering a visual programming GUI to experiment with cryptographic procedures. The tool has been developed for simple and homophonic substitution ciphers. The CODEBREAKER is an interactive online tool for semi-automatic decryption of transcribed images containing ciphertext. The TRANSCIPT tool is aimed for the transcription of images in an interactive fashion by using image processing with clustering.
You may enter a text or upload a file to have it normalised, or you may download the necessary tools to do the normalisation locally on your own computer.
So far, a tool for spelling normalisation, where the historical spelling is automatically transformed to a modern spelling, is provided. Furthermore, we provide tools for the automatic processing of historical texts. You may also create your own language models, by uploading historical sources of your choice. We also provide language models derived from these historical sources which may be downloaded from the Language Models section. Currently, you may download historical corpora for fifteen different European languages: Czech, Dutch, English, French, German, Greek, Hungarian, Icelandic, Italian, Latin, Portuguese, Slovene, Spanish, and Swedish. HistCorp is a collection of historical corpora and other useful resources and tools for researchers working with historical text.
Due to license restrictions, some images of records are private and cannot be visualised or downloaded. Users with an account to the database can also upload and download ciphertexts and keys with metadata information and related documents. The database enables search and all records in the database are open to the public. The DECODE database contains a collection of digitized images of ciphertexts and encryption keys along with metadata information about their provenance, location, transcription, and possible cryptanalysis or commentary. Below we list resources and tools that we develop in more detail, which are described in our scientific papers listed here. The tools facilitate the processing of the encrypted sources from transcription to decryption incl. Resources are collections of encrypted sources, and historical texts and language models. Within the DE CRYPT project, we release resources and tools with open access to facilitate research in historical cryptology, allowing collection, analysis and decryption of historical ciphertexts. Our aim is to develop resources and computer-aided tools for decoding of historical source material by using AI and cross-disciplinary research involving computational linguistics, cryptology, history, linguistics and philology. The bulk of these historical manuscripts will remain undeciphered unless we can automate the processes involved in decoding them. Examples of such material are diplomatic correspondence and intelligence reports, private letters and diaries as well as manuscripts related to secret societies, or other (religious) groups in the margins of society. Thousands of enciphered historical manuscripts are buried in libraries and archives. The DE CRYPT Project: A utomatic D ecryption of H istorical Manuscripts
