I have been given the choice by a client of AES128 or 3DES encryption.
I have to roll it out on both iOS and Android.
Which will be easier to do?
Are there libraries for both iOS and Android?
Full or Partial answer would be great (i.e. if you only know about one platform)
Prefer AES128 over 3DES. 3DES provides an effective key size of 112 bits, while AES 128 uses 128 bits of key space.
