The final version of echo BAT encryption is an updated version of the BAT encryption tool, which has many advantages over the previous version of the encryption tool:

Echo.

Echo ★ can successfully encrypt any batch file at one time, making it easier.

Echo.

Echo ★ allows you to enter any batch that needs to be encrypted for greater encryption flexibility.

Echo.

Echo ★ can automatically judge the wrong input, making it more user-friendly.

Echo.

Echo description: enter the batch file that needs to be encrypted below, and directly enter the batch file name to encrypt the BAT under the current directory, or you can specify any BAT with a path. The encrypt.bat files generated under the current directory are encrypted batches.
