  2. Public-key cryptography - Wikipedia

    en.wikipedia.org/wiki/Public-key_cryptography

    In an asymmetric key encryption scheme, anyone can encrypt messages using a public key, but only the holder of the paired private key can decrypt such a message. The security of the system depends on the secrecy of the private key, which must not become known to any other.

  3. BackupHDDVD - Wikipedia

    en.wikipedia.org/wiki/BackupHDDVD

    The utility reads a text file containing volume or title keys and attempts to find a set of corresponding keys for the inserted disc. Through a standard AES library, it then decrypts each video file on the disc using the appropriate keys and writes the results to a location specified by the user. Direct file decryption allows the utility's ...

  4. Data Protection API - Wikipedia

    en.wikipedia.org/wiki/Data_Protection_API

    When installing a new domain on a domain controller, a public and private key pair is generated, associated with DPAPI. When a master key is generated on a client workstation, the client communicates through an authenticated RPC call with a domain controller to retrieve a copy of the domain's public key. The client encrypts the master key with ...

  5. PKCS 11 - Wikipedia

    en.wikipedia.org/wiki/PKCS_11

    In cryptography, PKCS #11 is a Public-Key Cryptography Standards that defines a C programming interface to create and manipulate cryptographic tokens that may contain secret cryptographic keys. It is often used to communicate with a Hardware Security Module or smart cards .

  6. DeCSS - Wikipedia

    en.wikipedia.org/wiki/DeCSS

    When the release of the DeCSS source code made the CSS algorithm available for public scrutiny, it was soon found to be susceptible to a brute-force attack quite different from DeCSS. The encryption is only 40-bit , and does not use all keys; a high-end home computer in 1999 running optimized code could brute-force it within 24 hours, and ...

  7. PKCS 7 - Wikipedia

    en.wikipedia.org/wiki/PKCS_7

    PKCS #7 files may be stored both as raw DER format or as PEM format. PEM format is the same as DER format but wrapped inside Base64 encoding and sandwiched in between ‑‑‑‑‑BEGIN PKCS7‑‑‑‑‑ and ‑‑‑‑‑END PKCS7‑‑‑‑‑. Windows uses the .p7b file name extension [6] for both these encodings.

  8. EFF DES cracker - Wikipedia

    en.wikipedia.org/wiki/EFF_DES_cracker

    In cryptography, the EFF DES cracker (nicknamed "Deep Crack") is a machine built by the Electronic Frontier Foundation (EFF) in 1998, to perform a brute force search of the Data Encryption Standard (DES) cipher's key space – that is, to decrypt an encrypted message by trying every possible key.

  9. Threshold cryptosystem - Wikipedia

    en.wikipedia.org/wiki/Threshold_cryptosystem

    The message is encrypted using a public key, and the corresponding private key is shared among the participating parties. With a threshold cryptosystem, in order to decrypt an encrypted message or to sign a message, several parties (more than some threshold number) must cooperate in the decryption or signature protocol.
