Is Abstract Algebra Essential for CS Majors in Understanding Cryptography?

[PhDorBust]

As a CS major is it profitable to take more esoteric mathematics courses such as topology or abstract algebra? Or should I concentrate on more typical CS math such as discrete math, number theory, graph theory, etc.

If you plan on taking mathematical logic, then abstract algebra may prove useful.

You will also find that abstract algebra is important if you ever want to have any hope of understanding the why behind most of cryptography.
