  2. RSA problem - Wikipedia

    en.wikipedia.org/wiki/RSA_problem

    In cryptography, the RSA problem summarizes the task of performing an RSA private-key operation given only the public key. The RSA algorithm raises a message to an exponent, modulo a composite number N whose factors are not known. Thus, the task can be neatly described as finding the e th roots of an arbitrary number, modulo N.

    But, some algorithms like BitLocker and VeraCrypt are generally not private-public key cryptography. For example, Veracrypt uses a password hash to generate the single private key. However, it can be configured to run in public-private key systems. The C++ opensource encryption library OpenSSL provides free and opensource encryption software ...

    en.wikipedia.org/wiki/Security_protocol_notation

    A key with one subscript, K A, is the public key of the corresponding individual. A private key is represented as the inverse of the public key. The notation specifies only the operation and not its semantics — for instance, private key encryption and signature are represented identically. We can express more complicated protocols in such a ...

    However, current key sizes would all be cracked quickly with a powerful quantum computer. [citation needed] “The keys used in public key cryptography have some mathematical structure. For example, public keys used in the RSA system are the product of two prime numbers.

  6. McEliece cryptosystem - Wikipedia

    en.wikipedia.org/wiki/McEliece_cryptosystem

    The public key is derived from the private key by disguising the selected code as a general linear code. For this, the code's generator matrix is perturbated by two randomly selected invertible matrices and (see below). Variants of this cryptosystem exist, using different types of codes.

  7. PKCS - Wikipedia

    en.wikipedia.org/wiki/PKCS

    In cryptography, PKCS (Public Key Cryptography Standards) are a group of public-key cryptography standards devised and published by RSA Security LLC, starting in the early 1990s. The company published the standards to promote the use of the cryptography techniques for which they had patents , such as the RSA algorithm , the Schnorr signature ...

  8. PKCS 12 - Wikipedia

    en.wikipedia.org/wiki/PKCS_12

    In cryptography, PKCS #12 defines an archive file format for storing many cryptography objects as a single file. It is commonly used to bundle a private key with its X.509 certificate or to bundle all the members of a chain of trust. A PKCS #12 file may be encrypted and signed.

  9. Key encapsulation mechanism - Wikipedia

    en.wikipedia.org/wiki/Key_encapsulation_mechanism

    A key encapsulation mechanism, to securely transport a secret key from a sender to a receiver, consists of three algorithms: Gen, Encap, and Decap. Circles shaded blue—the receiver's public key and the encapsulation —can be safely revealed to an adversary, while boxes shaded red—the receiver's private key and the encapsulated secret key —must be kept secret.
