  Implementing DESede/ECB/NoPadding cipher algorithm in GoLang

By default, GoLang doesn't provide the ECB mode cipher for DESede though there is CBC mode provided. In cases we need to encrypt/decrypt data with ECB mode, we need to implement those by ourselves. This mode is frequently used when encrypting/decrypting PIN block which is small block data less than 16 bytes. In this post, we will introduce how to implement the DESede/ECB/NoPadding algorithm in GoLang by using the existing cipher support. Here we will not cover how DESede works in detail, instead...

  JS code to check different mobile devices

Today I come across a code snippet which uses JavaScript to check different mobile devices and then loads different CSS files accordingly. As we know that there are mobile devices with different screen sizes, it's always troublesome for web developers to develop cross browser and cross device compatible codes.
