c# - BouncyCastle Symmetric Cipher algorithm with output same length as input -


i'm trying create bouncycastle cipher algorithm using csharp api meets following criteria:

  • output same length input
  • small variations in input (a few bytes) produce large variation in output
  • handles small input (between 10 , 16 bytes)

any appreciated

edit: have tried aes/ctr/nopadding while meets first , third criteria doesn't meet second - repeated encryption small variations in input produced minor changes in output.
