PKCS#9 OID Constants
PKCS#9 attribute OIDs are available from two locations:
synta.pkcs9— a dedicated module with the full PKCS#9 arc (13 constants)synta.oids— the top-level OID catalog (9 of the most common constants)
From synta.oids
import synta.oids as oids
oids.PKCS9_EMAIL_ADDRESS # 1.2.840.113549.1.9.1 — emailAddress

oids.PKCS9_SIGNING_TIME # 1.2.840.113549.1.9.5 — id-signingTime
oids.PKCS9_COUNTERSIGNATURE # 1.2.840.113549.1.9.6 — id-countersignature
oids.PKCS9_CHALLENGE_PASSWORD # 1.2.840.113549.1.9.7 — id-challengePassword
