getDigest
public byte[] getDigest()
throws java.io.IOException
- Get the digest for our input stream.
This method constructs the input stream digest, and return it, as a
a String, following the MD5 (rfc1321) algorithm,
- Returns:
- An instance of String, giving the message digest.
- Throws:
java.io.IOException - Thrown if the digestifier was unable to read the
input stream.
processString
public byte[] processString()
- Get the digest, for this string digestifier.
This method doesn't throw any IOException, since it knows that the
underlying stream ws built from a String.
getStringDigest
public java.lang.String getStringDigest()
- Get the digest, as a proper string.
createStringDigest
public static java.lang.String createStringDigest(java.lang.String aString)
throws java.io.IOException
main
public static void main(java.lang.String[] args)
throws java.io.IOException
