The Enrollment over Secure Transport, or EST is a cryptographic protocol that describes an X.509 certificate management protocol targeting public key infrastructure (PKI) clients that need to acquire client certificates and associated certificate authority (CA) certificates. EST is described in RFC 7030.
A Certification Practice Statement (CPS) is a document from a certificate authority or a member of a web of trust which describes their practice for issuing and managing public key certificates. [1] Some elements of a CPS include documenting practices of: issuance; publication; archiving; revocation; renewal
In cryptography, rekeying refers to the process of changing the session key—the encryption key of an ongoing communication—in order to limit the amount of data encrypted with the same key. Roughly equivalent to the classical procedure of changing codes on a daily basis , the key is changed after a pre-set volume of data has been transmitted ...
In cryptography, X.509 is an International Telecommunication Union (ITU) standard defining the format of public key certificates. [1] X.509 certificates are used in many Internet protocols, including TLS/SSL, which is the basis for HTTPS, [2] the secure protocol for browsing the web.
In cryptography, a public key certificate, also known as a digital certificate or identity certificate, is an electronic document used to prove the validity of a public key. [ 1 ] [ 2 ] The certificate includes the public key and information about it, information about the identity of its owner (called the subject), and the digital signature of ...
These shortcuts, also called hotkeys, consist of two or more keys pressed at the same time. Here are some of the most useful Excel hotkeys to make a wide range of spreadsheet tasks easier ...

In cryptography and computer security, a root certificate is a public key certificate that identifies a root certificate authority (CA). [1] Root certificates are self-signed (and it is possible for a certificate to have multiple trust paths, say if the certificate was issued by a root that was cross-signed) and form the basis of an X.509 ...
