ent binary package in Ubuntu Focal amd64

 This program applies various tests to sequences of bytes stored in
 files and reports the results of those tests. The program is useful
 for those evaluating pseudorandom number generators for encryption and
 statistical sampling applications, compression algorithms, and other
 applications where the information density of a file is of interest.
