require 'chilkat'

# Note: Requires Chilkat v9.5.0.65 or greater.

sb = Chilkat::CkStringBuilder.new()
sb.Append("The 5 men of 223rd St")
print sb.getAsString() + "\n";

# 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() + "\n";

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

# Decode back to the original string.
sb.Decode("eda","utf-8")
print sb.getAsString() + "\n";
print "----" + "\n";

# 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 = Chilkat::CkCrypt2.new()
crypt.put_CryptAlgorithm("aes")
crypt.put_CipherMode("cbc")
crypt.put_KeyLength(256)
crypt.put_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 + "\n";

# Now decrypt:
decStr = crypt.decryptStringENC(encStr)
print decStr + "\n";
