-## Difference between OSCP and CRL Distribution Points
+## Difference between OCSP and CRL Distribution Points
 
 **OCSP** (RFC 2560) is a standard protocol that consists of an **OCSP client and an OCSP responder**. This protocol **determines revocation status of a given digital public-key certificate** **without** having to **download** the **entire CRL**.\
 **CRL** is the **traditional method** of checking certificate validity. A **CRL provides a list of certificate serial numbers** that have been revoked or are no longer valid. CRLs let the verifier check the revocation status of the presented certificate while verifying it. CRLs are limited to 512 entries.\
