Hi,
I have been reading Optimized Homomorphic Encryption Solution for Secure Genome-Wide Association Studies and in section II-J2 “Evaluation Key compression” is mentioned.
Is there an API available for removing or compressing the rotation keys that are not going to be used after a certain point in the program?
Thanks,
Eymen

Forgot to mention that I use CKKS.
Currently, this functionality is not available in OpenFHE. There is an issue created for this Add functionality for creating automorphism keys at a specified level · Issue #413 · openfheorg/openfhe-development · GitHub, and it will be added in the future. You can look at it to see more information (a limited version of compression was available in Palisade).
There is prototype for this (works only for BV key switching) at openfhe-genomic-examples/demo-logistic.cpp at main · openfheorg/openfhe-genomic-examples · GitHub (also check the lines calling SetKeyGenLevel)
