About DECODE

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. The database enables search and the user can upload and download ciphertexts and keys with metadata information. The transcriptions can be used for training automatic cryptology tools. Due to license restrictions, some images cannot be downloaded but are shown as miniature.
