Keeping Secrets: Setting a Cipher Mode
Jan 29,
2016
Earlier this week we considered ways to split the many choices of ciphers (or encryption algorithms): symmetric versus asymmetric, and block versus stream. The block symmetric ciphers do the heavy lifting, they are used for large data sets. But one block symmetric cipher can be operated in various modes, and the selection of mode depends […]

So you want to encrypt your sensitive information to protect its confidentiality. Good! But exactly how should this be done? There are many ciphers (or encryption algorithms) to choose from. Let’s see what choices are available. Splitting the Choices Selecting a cipher is like sharing bread with your friend. Wait. What? Let’s say you want […]
