    if (input == null) {
        return null;
    }
    MessageDigest digest;
    try {
        digest = MessageDigest.getInstance("MD5");

    } catch (Exception e) {
        throw new UnexpectedLiquibaseException(e);
    }
    byte[] digestBytes = digest.digest();
    String returnString = new String(encodeHex(digestBytes));
    String inputToLog = input;
    if (inputToLog.length() > 500) {
        inputToLog = inputToLog.substring(0, 500) + "... [truncated in log]";
    }
    LogFactory.getLogger().debug("Computed checksum for " + inputToLog + " as " + returnString);
    return returnString;
