Load Base64-encoded X.509 Certificate (.cer)

See more Certificates Examples

Loads a digital certificate from a base64 encoded DER X.509 Certificate (.cer, .crt) and fetches information about the cert. Ruby

require 'chilkat'

success = false

cert = Chilkat::CkCert.new()

# LoadFromFile will load virtually any certificate format file.
# It will auto-recognize the format and load appropiately.
# A base64-encoded DER X.509 certificate file
# contains the binary DER in base64 encoded form.
# Therefore, it is a text file that will begin like this:
# -----BEGIN CERTIFICATE-----
# MIIFbjCCBFagAwIBAgIGdDPNv/L0MA0GCSqGSIb3DQEBBQUAMIHKMQswCQYDVQQG
# EwJVUzEQMA4GA1UECBMHQXJpem9uYTETMBEGA1UEBxMKU2NvdHRzZGFsZTEaMBgG
# ...

success = cert.LoadFromFile("/Users/chilkat/testData/cer/chilkat_base64.cer")
if (success != true)
    print cert.lastErrorText() + "\n";
    exit
end

# DN = "Distinguished Name"
print "SubjectDN:" + cert.subjectDN() + "\n";

print "Common Name:" + cert.subjectCN() + "\n";
print "Issuer Common Name:" + cert.issuerCN() + "\n";

print "Serial Number:" + cert.serialNumber() + "\n";
