BASE64Encoder
Hello All
I have this code
String s = null;
s = "somevalue";
BASE64Encoder encoder = new BASE64Encoder();
String encoded = encoder.encodeBuffer(s.get
return encoded;
The value returned has a carriage return, so when i insert this value into a db table and do a select where clause the value isn't picked up as the select statement looks like this
select * from table where encoded = 'fklgjfjglfjklgjf'
But if i do this
select * from table where encoded = 'fklgjfjglfjklgjf
'
It works
Can anyone tell me how i get rid of the carriage return ?
Many Thanks
From your select statements it looks like the offending character is at the end of the string. In that case the simple solution would be something like:
String s = null;
s = "somevalue";
BASE64Encoder encoder = new BASE64Encoder();
String encoded = encoder.encodeBuffer(s.get
return encoded.substring(0,encode
String s = null;
s = "somevalue";
BASE64Encoder encoder = new BASE64Encoder();
String encoded = encoder.encodeBuffer(s.get
return encoded.substring(0,encode
Let's look at this a different way - firstly, why are you saving something as Base64?
ASKER
what should i be saving it as then?
There are other options, but without knowing why you're using this method, it's hard to comment

I just want ot encypt a string - that's all, so pass a string into the method and return an encrypted version of is
e.g. normal string = mystring
encrypted string = hjgjkf898TWQ890585jkjk9545
Well Base64's purpose is not for encryption - it offers negligible protection. Do you want to encrypt it two-way or one-way?
ASKER
one-way
But can you show me 2-way as well :)
If it's one-way, then you would be best off using MessageDigest with SHA1. Practicably uncrackable.
Two-way - see the following (and related links):

ASKER
do you have an example of messagedigest with sha1 ?
You can use this to give you a hash you can read (but not decrypt) and save in your db:
public static String getDigest(String s) {
try {
MessageDigest md = MessageDigest.getInstance(
byte[] bytes = md.digest(s.getBytes());
return new BigInteger(1, bytes).toString(16);
} catch (NoSuchAlgorithmException e) {
e.printStackTrace();
}
return null;
}
public static String getDigest(String s) {
try {
MessageDigest md = MessageDigest.getInstance(
byte[] bytes = md.digest(s.getBytes());
return new BigInteger(1, bytes).toString(16);
} catch (NoSuchAlgorithmException e) {
e.printStackTrace();
}
return null;
}

Cheers
Works much better

Try this
byte[] sUserIdBytes = s.getBytes();
BASE64Encoder encoder = new BASE64Encoder();
String encoded = encoder.encode(sUserIdByte
return encoded ;
