That's terrific Rob!
Great work!!

Never mind, I found it. There is new code in BlockCipherMode>>#vector: which destroys the vector getting replaced. I was using the same ByteArray to initialize both the encryptor and decryptor, and it was getting destroyed before the decryptor could use it.
All tests, 90 of em, pass. All is green.

I was running the unit tests and I noticed that 2 of my own tests are now failing. This wasn't the case 6 months ago. One test is for DES-CBC and the other is for TripleDES-CBC. Did some code change in this area recently?
Here is a little detail for the test #testDESCBC
startBuffer = a ByteArray(1 35 69 103 137 171 205 231) 1st encrypt = a ByteArray(157 97 0 32 114 216 222 93) 1st decrypt = a ByteArray(1 50 103 84 205 254 171 144) 2nd encrypt = a ByteArray(14 235 75 121 46 119 224 35) 2nd decrypt = a ByteArray(1 50 103 84 205 254 171 144)
What is strange is that while the 1st decrypt is different than the startBuffer, the 2nd decrypt equals the first decrypt. This is true even though the corresponding encrypts are different. Anyway, the 1st decrypt is sufficient to show a problem.
Could someone look into this who has DES knowledge?
I am away for the next week, so I won't be able to respond.
