	version: 2.0.2-RELEASE

Missing required options: '--secret-key', '--source-file=<source file>'
Usage: encrypt-dog [-dehoV] -k [-k]... [-a=<encryptAlgorithm>] [-t=<storage
                   path>] -s=<source file>[,<source file>...]... [-s=<source
                   file>[,<source file>...]...]...
  -a, --encrypt-algorithm=<encryptAlgorithm>
                     The default encryption algorithm is AES. Currently
                       supported encryption algorithms are AES, DESede (3DES),
                       and XOR.
  -d, --delete       The source file is not deleted after the default operation.
  -e, --encrypt      The default is decryption mode.
  -h, --help         Show this help message and exit.
  -k, --secret-key   Both encrypt and decrypt require the same secret key
  -o, --only-local   Encryption and decryption operations can only be performed
                       on the same physical device.Only Apple Mac is supported
  -s, --source-file=<source file>[,<source file>...]...
                     Target files that need to be encrypt and decrypt,Wildcards
                       are supported.
  -t, --target-path=<storage path>
                     The storage path after the operation is stored in the
                       original path by default.
  -V, --version      Print version information and exit.

highest security

Files encrypted on computer a can only be decrypted on computer a.
Principle:

WARN:

Deleting or damaging the random key will never complete decryption.
