In cryptography, a padded uniform random blob or PURB is a discipline for encrypted data formats designed to minimize unintended information leakage either from its encryption format metadata or from its total length. == Properties of PURBs == When properly created, a PURB's content is indistinguishable from a uniform random bit string to any observer without a relevant decryption key.
