Make SHA1 encryption on Android?

Question

Can you suggest me about how to encrypt string using SHA1 algorithm ? I\'ve searched about it. But no luck.

Thanks in advance.

binnyb set me on the right track, but I found some more, easier to understand code here: http://www.coderanch.com/t/526487/java/java/Java-Byte-Hex-String

private static String convertToHex(byte[] data) {
    StringBuilder sb = new StringBuilder(data.length * 2);

    Formatter fmt = new Formatter(sb);
    for (byte b : data) {
        fmt.format("%02x", b);
    }

    return sb.toString();
}
