Shared Interface with a "crit" property for all sign, verify, encrypt and decrypt operations.
Properties
crit?
• optional crit?: object
An object with keys representing recognized "crit" (Critical) Header Parameter names. The value
for those is either true or false. true when the Header Parameter MUST be integrity
protected, false when it's irrelevant. The JWS extension Header Parameter b64 is always
recognized and processed properly; no other registered Header Parameters currently receive this
built-in treatment.
Warning
This only checks that the Header Parameter is syntactically correct when provided and,
optionally, integrity protected. It does not process the Header Parameter or reject the
operation when it is missing. You MUST still verify its presence and process it according to
the profile's validation steps after the operation succeeds.
