#  This example requires the Chilkat API to have been previously unlocked.
#  See Global Unlock Sample for sample code.

pfx = chilkat.CkPfx()

success = pfx.LoadPfxFile("qa_data/pfx/myEccCert.p12","MY_ECC_PFX_PASSWORD")
if (success == False):
    print(pfx.lastErrorText())
    sys.exit()

#  To get the contents of the PFX in JWK Set form, we must first convert
#  to a Java KeyStore object:
#  The alias will become the key id ("kid") the the JWK Set.
#  The password is an input argument that becomes the password for the JavaKeyStore.
alias = "my_ecc_key"
password = "secret123"
jks = chilkat.CkJavaKeyStore()
success = pfx.ToJksObj(alias,password,jks)
if (success == False):
    print(pfx.lastErrorText())
    sys.exit()

sbJwkSet = chilkat.CkStringBuilder()
#  The ToJwkSet method writes to sbJwkSet.
success = jks.ToJwkSet(password,sbJwkSet)
if (success == False):
    print(jks.lastErrorText())
    sys.exit()

jwkSet = chilkat.CkJsonObject()
jwkSet.LoadSb(sbJwkSet)
jwkSet.put_EmitCompact(False)

print(jwkSet.emit())

#  The output is:
