X.509
In cryptography, X.509 is an ITU-T standard for a public key infrastructure (PKI) and Privilege Management Infrastructure (PMI). X.509 specifies, amongst other things, standard formats for public key certificates, certificate revocation lists, attribute certificates, and a certification path validation algorithm.
History and usage
X.509 was initially issued on July 3, 1988 and was begun in association with the X.500 standard. It assumes a strict hierarchical system of certificate authorities (CAs) for issuing the certificates. This contrasts with web of trust models, like PGP, where anyone (not just special CAs) may sign and thus attest to the validity of others' key certificates. Version 3 of X.509 includes the flexibility to support other topologies like bridges and meshes. It can be used in a peer-to-peer, OpenPGP-like web of trust, but was rarely used that way as of 2004. The X.500 system has only ever been implemented by sovereign nations for state identity information sharing treaty fulfillment purposes, and the IETF's Public-Key Infrastructure (X.509), or PKIX, working group has adapted the standard to the more flexible organization of the Internet. In fact, the term X.509 certificate usually refers to the IETF's PKIX Certificate and CRL Profile of the X.509 v3 certificate standard, as specified in RFC 5280., commonly called PKIX for Public Key Infrastructure (X.509).

Beach Boys
by: Beach BoysUnfolding enveloping missiles of soul
Recall senses sadly
Mirage like soft blue like lanterns below
To light the way gladly
Whether whistling heaven's clouds disappear
Where the wind withers memory
Whether whiteness whisks soft shadows away
Feel flows (White hot glistening shadowy flows)
Feel goes (Black hot glistening shadowy flows)
Unbending never ending tablets of time
Record all the yearning
Unfearing all appearing message divine
Eases the burning
Whether willing witness waits at my mind
Whether hope dampens memory
Whether wondrous will stands tall at my side
Feel flows (White hot glistening shadowy flows)
Feel goes (Black hot glistening shadowy flows)
Encasing all embracing wreath of repose
Engulfs all the senses
Imposing, unclosing thoughts that compose
Retire the fences
Whether wholly heartened life fades away
Whether harps heal the memory
Whether wholly heartened life fades away
Whether wondrous will stands tall at my side
Whether whiteness whisks soft shadows away
Feel goes (White hot glistening shadowy flows)
Feel flows (Black hot glistening shadowy flows)
Feel goes (White hot glistening shadowy flows)
Feelings to grow (White hot glistening shadowy flows)
White hot glistening shadowy flows
White hot glistening shadowy flows
