Answers to Questions (FAQ)
How to decrypt a nothing text?
To decrypt / decipher an encoded message, it is necessary to know the encryption used (or the encoding method, or the implemented cryptographic principle). Without knowing the technique chosen by the sender of the message, it is incommunicable to decrypt it (or decode it). Knowing the encryption (or encoding, or code) is therefore the outset stride to outset the decryption (or decoding) process.
dCode therefore proposes, on this folio above, an artificial intelligence tool defended to the automatic recognition/identification of encryption and direct links to tools capable of deciphering the message/text.
How to recognize a cipher?
To recognize/guess the type of encryption/encoding used to encrypt/encode a message, dCode uses several detection/cryptanalysis methods:
— frequency analysis: which characters of the message appear near oft? In what proportion? Which characters exercise not appear? This analysis tin can be carried out for all the characters (but often the letters A-Z and the numbers 0-ix allow to eliminate many methods of ciphers/coding). The analysis of bigrams or trigrams (or more generally group of letters) makes it possible to refine the cryptanalysis, the presence or absence of certain groups of messages are clues.
— the coincidence alphabetize: how random are the characters of the bulletin? Intelligible letters (in English) tend to favor certain letters and practice non use the Eastward in the same fashion as the X (much rarer).
— signature search: certain ciphers / encodings take characteristic marks, a signature which makes them identifiable.
Example: The base64 code contains all the possible numbers and letters (upper and lower example) distributed fairly evenly just 3 times out of 4, information technology ends with the sign =.
When the message is accompanied by instructions or clues, some keywords can trigger more results from the dCode database. NB: do not betoken known plaintext.
Why does the detector brandish a warning?
Sometimes the cipher identifier finds little or no relevant result, several reasons are possible:
— The message is too short: a message containing not enough characters does not allow a skilful frequency assay to exist performed. The possibilities get very numerous without a way to precisely identify the encryption.
— The message has a depression entropy: it is composed of few distinct characters (a binary message containing only 0s and 1s has a low entropy). Furthermore, almost all messages can be stored in binary, identifying the encryption precisely is difficult.
— The message is over-encrypted: several successive encodings / ciphers have been applied, the over-encryption tends to mask the characteristic signatures of the original encryption.
— The encryption used is contempo: mod cryptography techniques are such that it is impossible to recognize an encrypted message from a random message, it is moreover a quality of a skilful encryption. Identification is, in essence, difficult.
— The encryption used is very rare: dCode tin detect nearly 200 dissimilar ciphers and continues to improve thanks to your feedback and messages, but it is not impossible that some ciphers are still unknown/missing.
Why does the analyzer/recognizer not notice my nix method?
Sometimes the recognizer algorithm (based on bogus intelligence and machine learning) finds multiple signals, distinctive signs from several cypher types, and returns approximate results. Please contact usa with your naught message, the original message and the encryption method used and then that dCode tin can teach the analyzer this encryption for future times. The more data there is, the more than accurate the detection will exist.
