undecodable

Impossible to crack

Unable to be decoded or deciphered.

Something undecodable resists interpretation—whether encrypted data without a key, a corrupted file, or handwriting too messy to read: The message remained undecodable without the cipher.

The term appears in technical contexts involving encryption, linguistics, and signal processing.
