About certificate formats

Encodings

• X.509 is expressed in the formal notation Abstract Syntax Notation One (ASN.1)
• Distinguished Encoding Rules (DER) is a binary encoding of ASN.1
• Privacy Enhanced Mail (PEM) is a base64 encoding of DER

.cer, .crt

A file with the extension .crt or .cer, contains a single X.509 certificate using

def Secured[A](username: String, password: String)(action: Action[A]) = Action(action.parser) { request =>
  request.headers.get("Authorization").flatMap { authorization =>
    authorization.split(" ").drop(1).headOption.filter { encoded =>
      new String(org.apache.commons.codec.binary.Base64.decodeBase64(encoded.getBytes)).split(":").toList match {
        case u :: p :: Nil if u == username && password == p => true
        case _ => false
      }
    }.map(_ => action(request))
  }.getOrElse {
    Unauthorized.withHeaders("WWW-Authenticate" -> """Basic realm="Secured"""")

Installing ZFS on Linux on Oracle Linux 7

We're going to add ZFS support to our Oracle Linux installation. We'll just add the ZFS on Linux Repo, verify the binary signature from GitHub, install the files, ensure the driver loads properly, and verify that it's functional. We'll save things like array creation for another document.

This is mostly a transcription of the process from the CentOS/RHEL ZoL installation manual.

Note

This will install ZFS v0.7 release on OEL 7.7 and earlier, and ZFS 0.8 on OEL 7.8 and later.

Install the repo file
