Chiffré

Chiffré is a term derived from the French word for "cipher" or "coded." In various contexts, it refers to something that has been encoded, encrypted, or written in a secret script. The precise meaning can vary depending on the field, but the core concept revolves around making information obscure or unintelligible to unauthorized individuals.

In cryptography, chiffré directly relates to the process of encryption, where plain text is transformed into ciphertext using an algorithm and a key. The resulting chiffré text is then indecipherable without the corresponding decryption key. Historically, chiffré techniques have been employed for secure communication, ranging from simple substitution ciphers to more complex modern encryption methods.

Beyond cryptography, the term chiffré can also be used more broadly to describe any form of coded language, secret writing, or even symbolic representation that requires a specific understanding to interpret. For instance, artistic or literary works might be described as chiffré if they employ hidden meanings or codes that are not immediately apparent. The idea is that there is a layer of meaning or data that is not plainly visible and requires a specific key or knowledge to unlock.
