Senses
(O)
A certificate that is intended for use with both digital signature and data encryption services. [SP32]
Usage: IDOCs that use this term SHOULD state a definition for it by identifying the intended uses of the certificate, because there are more than just these two uses mentioned in the NIST publication. A v3 X.509 public-key certificate may have a "key
Usage" extension, which indicates the purposes for which the public key may be used. (See: certificate profile.)
