A combination of 32 characters consisting of letters and digits.


A combination of 32 characters consisting of:

  • a-f or A-F (case-sensitive)
  • or 0-9

for example:


Credential example

host:; apikey: abcdef0123456789abcdef0123456789;



SITs that have checksums use a unique calculation to check if the information is valid. This means when the Checksum value is Yes, the service can make a positive detection based on the sensitive data alone. When the Checksum value is No additional (secondary) elements must also be detected for the service to make a positive detection.

Keyword Highlighting


When keyword highlighting is supported in the contextual summary for a sensitive information type or a trainable classifier, in the Contextual Summary view of activity explorer, the keywords in a document that were matched to a policy are highlighted.


This SIT is designed to match the security information that's used to authenticate inbound requests to Azure Cognitive Search APIs.

It uses several primary resources:

Patterns of Hex encoded 128-bits symmetric key. Patterns of CredentialName, CredentialFeatures, AccountIdentityName, AccountIdentityValue, ResourceType, ResourceName. Patterns of mockup values, redactions, and placeholders. A dictionary of vocabulary.

The patterns are designed to match actual credentials with reasonable confidence. The patterns don't match credentials formatted as examples. Mockup values, redacted values, and placeholders, like credential type or usage descriptions, in the position where an actual secret value should present won't be matched.
