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

dsa = chilkat2.Dsa()

# Load a DER private key.
success = dsa.FromDerFile("dsa_priv.der")
if (success != True):
    print(dsa.LastErrorText)
    sys.exit()

# Save to unencrypted PEM:
pemStr = dsa.ToPem()
success = dsa.SaveText(pemStr,"dsa_priv.pem")
if (success != True):
    print(dsa.LastErrorText)
    sys.exit()

# Save to encrypted PEM:
pemStr = dsa.ToEncryptedPem("myPassword")
success = dsa.SaveText(pemStr,"dsa_privEncrypted.pem")
if (success != True):
    print(dsa.LastErrorText)
    sys.exit()
