Encrypted data cannot be accessed or recovered without this password. Glossary 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.
