AES counter mode

Hello,

I'm looking to implement encryption and transmission of large datasets
(in the order of a couple of gigabytes) with the following
requirements:

a) the encryption of each block shouldn't depend on the completed
encryption and transmission of other blocks (i.e. parallel encryption)

b) encryption and transmission may be stopped and it should be
possible to resume the encryption using as small a saved state as
possible (e.g. the key, the IV/nonce and the sequence of previously
encrypted blocks).

If I'm not mistaken AES CTR mode would be suitable for this task. Is
it possible with cryptlib? I haven't found any information about AES
CTR and cryptlib so far.

Is there perhaps some other way that I could implement (a) and (b)
that would be possible and/or straightforward with cryptlib?

Thank you,
Konstantinos
