Dim sb As New ChilkatStringBuilder
success = sb.Append("The 5 men of 223rd St")
Debug.Print sb.GetAsString()

' Encode the utf-8 byte representation of the string in the 
' UN/EDIFACT syntax level A character set.
success = sb.Encode("eda","utf-8")
Debug.Print sb.GetAsString()

' EDA Output should be: BTME027FCF6CFARFI94JT6.)F(14KJ2U

' Decode back to the original string.

' The following requires the Chilkat API to have been previously unlocked.
' See Global Unlock Sample for sample code.

' The "eda" encoding can be used anywhere within Chilkat.
' For example, with the Crypt2 API
Dim crypt As New ChilkatCrypt2
crypt.CryptAlgorithm = "aes"
crypt.CipherMode = "cbc"
crypt.KeyLength = 256
crypt.EncodingMode = "eda"

Dim ivHex As String
ivHex = "000102030405060708090A0B0C0D0E0F"
crypt.SetEncodedIV ivHex,"hex"
Dim keyHex As String
keyHex = "000102030405060708090A0B0C0D0E0F101112131415161718191A1B1C1D1E1F"
crypt.SetEncodedKey keyHex,"hex"

Dim encStr As String
encStr = crypt.EncryptStringENC("The quick brown fox jumps over the lazy dog.")
' The output is UN/EDIFACT syntax level A 
Debug.Print encStr

' Now decrypt:
Dim decStr As String
decStr = crypt.DecryptStringENC(encStr)
Debug.Print decStr
