S57 Encoder 1.0

S57 encoder is a text file encode and decode tool. S57 encoder will also compress the file before encoding.

Double click "S57 encoder.exe", then choose a file to encode or decode.
Or simply drag and drop a file onto "S57 encoder.exe"
Then enter the password.

"S57 encoder" will auto-detect the file type and start encoding or decoding accordingly.

The encoded file will have the same name with .enc" extension.
The decoded file will have the same name with .txt" extension.

The encoded or decoded file will be created in the same directory.
If the file already exists, it will be overwritten.

If you forgot the password or input a wrong password, the file will never be able to restore to its original.

For security reason, the password you enter will be erased from the memory upon termination of the program.

S57 encoder only supports two file types: ".txt" and ".enc" where the file with the extension ".enc" is its default encoded file type.
