CAUTION: Safeguard the Basic User password. Encrypted data cannot
be accessed or recovered without this password.
Certification Authority (CA)—a service that issues the certificates
required to run a public key infrastructure.
Cryptography—the practice and study of encryption and decryption;
encoding data so that it can only be decoded by specific individuals.
A system for encrypting and decrypting data is a cryptosystem. These
usually involve an algorithm for combining the original data
("plaintext") with one or more "keys"-numbers or strings of
characters known only to the sender and/or recipient. The resulting
output is known as "cipher text."
Cryptographic Service Provider (CSP)—a provider or library of
cryptographic algorithms that can be used in a well-defined interface
to perform particular cryptographic functions.
Decryption—any procedure used in cryptography to convert cipher
text (encrypted data) into plaintext.
Digital Certificates—electronic credentials that confirm the identity
of an individual or a company by binding the identity of the digital
certificate owner to a pair of electronic keys that are used to sign
digital information.
Digital Signature—feature used to verify the identity of the sender
of a digital document and certify that the contents were not modified
after the sender signed the document.
Emergency Recovery Archive—the archive is a protected storage
area that allows the re-encryption of basic user keys from one
platform owner key to another.
Encryption—i.e., algorithm, cryptography; any procedure used in
cryptography to convert plaintext into cipher text in order to prevent
unauthorized recipients from reading that data. There are many types
