SharePoint 2013 and SharePoint 2010 Claims Encoding

SharePoint 2013 and SharePoint 2010 display identity claims with the following encoding format:

Where:

<IdentityClaim> indicates the type of claim and is the following:
- “i” for an identity claim
- “c” for any other claim
<ClaimType> indicates the format for the claim value and is the following:
- “#” for a user logon name
- “.” for an anonymous user
- “5” for an email address
- “!” for an identity provider
- “+” for a Group security identifier (SID)
- “-“ for a role
- “%” for a farm ID
- “?” for a name identifier
- "\" for a private personal identifier (PPID)
<ClaimValueType> indicates the type of formatting for the claim value and is the following:
- “.” for a string
- “+” for an RFC 822-formatted name
<AuthMode> indicates the type of authentication used to obtain the identity claim and is the following:
- “w” for Windows claims (no original issuer)
- “s” for the local SharePoint security token service (STS) (no original issuer)
- “t” for a trusted issuer
- “m” for a membership issuer
- “r” for a role provider issuer
- “f” for forms-based authentication
- “c” for a claim provider
<OriginalIssuer> indicates the original issuer of the claim.
<ClaimValueType> indicates the value of the claim in the <ClaimType> format.

Here are some places in SharePoint where you will see claims encoding (please add to this list):

In the display of user sign-in information on a SharePoint 2010 or 2013 web site (For example, on a SharePoint 2013 team site page, click your user name in the upper-left corner, and then click My Settings. The Account field uses the claims encoding.)
In the "Authentication Authorization" log entries in the Unified Logging Service (ULS) log files for SharePoint 2013

Here are some examples (please add your own based on your experience):

Type of claim	Encoded claim	Claim encoding breakdown
Windows User	i:0#.w\|contoso\chris	“i” for an identity claim “#” for the user logon name format for the claim value “.” for a string “w” for Windows claims “contoso\chris” for the identity claim value (the Windows account name)
Windows Authenticated Users group	c:0!.s\|windows	“c” for a claim other than identity “!” for an identity provider “.” for a string “s” for the local SharePoint STS “windows” for the Windows Authenticated Users group
SAML authentication (Trusted User)	i:05.t\|adfs\|chris@contoso.com	“i” for an identity claim “5” for the email address format for the claim value “.” for a string “t” for a trusted issuer “adfs” identifies the original issuer of the identity claim “chris@contoso.com” for the identity claim value
Forms-based authentication	i:0#.f\|mymembershipprovider\|chris	“i” for an identity claim “#”for the user logon name format for the claim value “.” for string “f” for forms-based authentication “mymembershipprovider” identifies the original issuer of the identity claim “chris” for the user logon name
