Asymmetric Encryption and SSH Passwordless Login 1. Asymmetric Encryption In the digital age, asymmetric encryption technology forms the foundational pillar of our network security. This sophisticated cryptographic system uses a pair of mathematically related keys—public key and private key—to achieve a revolutionary breakthrough in secure communication. Core Features: • Unidirectionality: Content encrypted with the public … Read more
In the digital age, encryption algorithms serve as the “digital locks” that ensure information security. Their core essence is to transform plaintext (original information) into ciphertext that cannot be directly recognized, allowing only the recipient with the “key” (secret key) to restore the ciphertext back to plaintext, thus achieving secure transmission and storage of information. … Read more

As the “out-of-band management brain” of servers, the security of BMC chips is directly related to the safety of the entire server and even the data center. Therefore, data encryption and security measurement are among its primary functions, necessitating the inclusion of encryption and decryption modules in BMC chips. Recently, I conducted a brief study: … Read more
Overview The Linux Kernel Crypto API provides a rich set of encryption algorithms and other data transformation mechanisms, defining a unified method for invoking these mechanisms. In the Kernel Crypto API, all algorithms are collectively referred to as “transformations”; thus, handle variables related to cryptographic algorithms are typically named <span>tfm</span>. In addition to encryption operations, … Read more
