A simple tool to encrypt/decrypt file.

cipher build

builder, err := file_cipher.NewFileCipherBuilder(password)
if err != nil {
    panic(err)
}
fileCipher = builder.WithBufferSize(bufferSize).WithSignature(prefixBytes).Build()

encrypt

fileCipher.Encrypt(path, writer)
fileCipher.EncryptWithReader(reader, writer)

decrypt

fileCipher.Decrypt(path, writer)
fileCipher.DecryptWithReader(reader, writer)

batch encrypt/decrypt

file-cipher.exe -encrypt -password "your password" -buffer 4096 /path/to/file/*.txt
file-cipher.exe -decrypt -password "your password" -buffer 4096 /path/to/file/*.encrypt
