Note: This example requires Chilkat v11.0.0 or greater.

Chilkat Python Downloads install with pip pip3 install chilkat or download... Python Module for Windows, MacOS, Linux, Alpine Linux

import sys
import chilkat

success = False

cert = chilkat.CkCert()

success = cert.LoadFromFile("qa_data/certs/testCert.cer")
if (success == False):
    print(cert.lastErrorText())
    sys.exit()

# Get the certificate valid-from date/time
ckdt = chilkat.CkDateTime()
ckdt.SetFromRfc822(cert.validFromStr())

# Get the local timestamp string.
print("Valid from: " + ckdt.getAsTimestamp(True))
# Valid from: 2017-03-17T19:00:00-05:00

# Now get the date/time as another object where we can get the individual numeric date parts.
dt = chilkat.CkDtObj()
ckdt.ToDtObj(True,dt)

print(str(dt.get_Day()) + "/" + str(dt.get_Month()) + "/" + str(dt.get_Year()) + "  " + str(dt.get_Hour())\
     + ":" + str(dt.get_Minute()))

# Get the certificate valid-to date/time
ckdt.SetFromRfc822(cert.validToStr())

print("Valid to: " + ckdt.getAsTimestamp(True))
# Valid to: 2020-03-18T18:59:59-05:00new DtObj dt;
ckdt.ToDtObj(True,dt)

print(str(dt.get_Day()) + "/" + str(dt.get_Month()) + "/" + str(dt.get_Year()) + "  " + str(dt.get_Hour())\
     + ":" + str(dt.get_Minute()))
