Usage

install via glide

$ glide get github.com/qeek-dev/cryhel

// new crypto helper
c, err := cryhel.NewCrypto("AES256Key-32Characters1234567890") // default use Zero padding
c, err := cryhel.NewCryptoWithPadding("AES256Key-32Characters1234567890", cryhel.NewSpacePadding())

// encrypt (default base64 StdEncoding)
enc, err := c.Encrypt.Msg("string your want to encrypt").Do()

// Encrypt parameter support
// - StdEncoding
// - URLEncoding
// - RawStdEncoding
// - RawURLEncoding

// decrypt with default encoding: base64.StdEncoding

// decrypt with default encoding: base64.StdEncoding
