源码如下
public class MD5
{
public static String getMD5( String content )
{
try
{
MessageDigest digest = MessageDigest.getInstance( "MD5" );
digest.update( content.getBytes() );
return getHashString( digest );
} catch ( NoSuchAlgorithmException e )
{
e.printStackTrace();
}
return null;
}
private static String getHashString( MessageDigest digest )
{
StringBuilder builder = new StringBuilder();
for ( byte b : digest.digest() )
{
builder.append( Integer.toHexString( (b >> 4) & 0xf ) );
builder.append( Integer.toHexString( b & 0xf ) );
}
return builder.toString();
}
}
