the library expanded my skillset for industry, and on the scholar side it
keeps my research grounded in reality."

"I never truly got hands-on with OpenSSL until I heard about the native PQC support from version 3.5. Now, it has become my default choice for migrating infrastructure to post-quantum because it simplifies what used to be a complex integration."

"It was a joy to discover that OpenSSL has recently added PQC support for ML-DSA, ML-KEM, and LMS verification, which means I can finally stop dealing with multiple vendors and save time and resources."
