[openssl-users] openssl des-ede3-cbc does not match with Java one

[David García]

Hi,

I am trying to use openssl command line tool for des-ede3-cbc encryption,
but it does not mach with the one I have in Java (and that I know that
works ok). I try to generate a des-ede3-cbc encryption with an IV =
0,0,0,0,0,0,0,0. Then I launch following command:


echo 'text_to_cypher' | openssl enc -e -des-ede3-cbc -k
'b2aec78eb50e04f2a60b9efa20b82c903e3cad4f3bd2027g' -iv 00000000 -nosalt |
openssl enc -base64


But I don't get the same result as the one I get in Java using Cipher:

private final byte [] IV = {0, 0, 0, 0, 0, 0, 0, 0};
.....
DESedeKeySpec desKeySpec = new DESedeKeySpec(toByteArray(hexKey));
SecretKey desKey = new SecretKeySpec(desKeySpec.getKey(), "DESede");
Cipher desCipher = Cipher.getInstance("DESede/CBC/NoPadding");
desCipher.init(Cipher.ENCRYPT_MODE, desKey, new IvParameterSpec(IV));

//text 0 padding to get it multilpe of 8

byte[] ciphertext = desCipher.doFinal(cleartext);
new String(Base64.encodeBase64(ciphertext), "UTF-8");



Could anyone point me to what I am doing worng in this command line call?

Thanks in advance.
