The journal of Groups, Complexity, Cryptology is a peer-reviewed journal, dedicated to the publication of articles in the areas of combinatorial and computational group theory, complexity theory, and cryptology. Papers that touch upon at least two of these areas are particularly appreciated. The journal primarily publishes research papers, but comprehensive and timely survey articles on a topic within the scope of the journal are also welcome. 
The journal was published by Heldermann Verlag in 2009 and by Walter de Gruyter from 2010 to 2019 under the title Groups, Complexity, Cryptology. The move to a non-commercial platform was made in 2020 to adhere to the principles of truly open access where neither the readers nor the authors are charged.
