(Chilkat2-Python) RSASSA-PSS Algorithm with SHA256 Hashing
RSA encrypt a SHA256 hash with OAEP padding.

import chilkat2
# This example requires the Chilkat API to have been previously unlocked.
# See Global Unlock Sample for sample code.
privkey = chilkat2.PrivateKey()
# Load the private key object from a PEM file.
# (To load from a PEM string, call LoadPem instead.)
success = privkey.LoadPemFile("somePath/myPrivateKey.pem")
if (success != True):
print(privkey.LastErrorText)
sys.exit()
rsa = chilkat2.Rsa()
# Use RSA-PSS by setting OaepPadding = True
rsa.OaepPadding = True
# Use SHA256
rsa.OaepHash = "SHA-256"
rsa.ImportPrivateKeyObj(privkey)
# Generate a base64 signature.
rsa.EncodingMode = "base64"

if (rsa.LastMethodSuccess != True):
print(rsa.LastErrorText)
