import chilkat2

# Note: Requires Chilkat v9.5.0.65 or greater.

sb = chilkat2.StringBuilder()
sb.Append("The 5 men of 223rd St")
print(sb.GetAsString())

# Encode the utf-8 byte representation of the string in the 
# UN/EDIFACT syntax level A character set.
sb.Encode("eda","utf-8")
print(sb.GetAsString())

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

# Decode back to the original string.
sb.Decode("eda","utf-8")
print(sb.GetAsString())
print("----")

# 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
crypt = chilkat2.Crypt2()
crypt.CryptAlgorithm = "aes"
crypt.CipherMode = "cbc"
crypt.KeyLength = 256
crypt.EncodingMode = "eda"

ivHex = "000102030405060708090A0B0C0D0E0F"
crypt.SetEncodedIV(ivHex,"hex")
keyHex = "000102030405060708090A0B0C0D0E0F101112131415161718191A1B1C1D1E1F"
crypt.SetEncodedKey(keyHex,"hex")

encStr = crypt.EncryptStringENC("The quick brown fox jumps over the lazy dog.")
# The output is UN/EDIFACT syntax level A 
print(encStr)

# Now decrypt:
decStr = crypt.DecryptStringENC(encStr)
print(decStr)
