Implementation of DES algorithm in golang.

DES uses 64-bits block to processing the encryption. So you can't run go-DES on a 32-bits architecture.

$ go build -o go-des ./cmd/main.go

Example:

$ go-DES -e "I am a message to encrypt": Will encrypt the message in binary
$ go-DES -e -b "I am a message to encrypt": Will encrypt the message in binary
$ go-DES -e -h "I am a message to encrypt": Will encrypt the message in hexadecimal
$ go-DES -e -b64 "I am a message to encrypt": Will encrypt the message in base64
$ go-DES -d -h "762336c2b5360cc38751": Will decrypt the hexadecimal message

Arguments:

• --help: Print this helper
• -e: Encrypt a message
• -d: Decrypt a message
• -h: Use hexadecimal
• -b64: Use base64
• -b: Use binary

After entering the command you will be asked to enter an encryption/decryption key. Key lenght must be between 1 and 8 bytes (8 to 64 bits).
