Is RSA encryption with a private key the same as signature generation? KevinBlandy: # AttributeError: 'PublicKey' object has no attribute 'blinded_decryptĭon’t try to use a public RSA key to decrypt, and by extension, don’t try to use a private RSA key to encrypt: Many people say that RSA private key encryption has some security problems. Is there something wrong with my operation? I learned about this problem in search engine. Text = rsa.decrypt(base64.b64decode(base64Text.encode()), publicKey) # AttributeError: 'PublicKey' object has no attribute 'blinded_decrypt' Text = rsa.decrypt(base64.b64decode(base64Text.encode()), privateKey)Ĭipher = rsa.encrypt(b'Hello World!', privateKey) I try to use code to describe my purpose import rsaĬipher = rsa.encrypt(b'Hello World!', publicKey)īase64Text = base64.b64encode(cipher).decode() The code outputs the unencrypted PEM encoded PKCS#8 key.I am not very good at English.

Print(keyViaP圜ryptodome.exportKey(format='PEM', passphrase=None, pkcs=8, protection=None).decode('utf-8')) KeyViaP圜ryptodome = RSA.import_key(pkcs1_enc, b'1234') Print(keyViaHazmat.private_bytes(, 8, serialization.NoEncryption()).decode('utf-8')) KeyViaHazmat = serialization.load_pem_private_key(pkcs1_enc, b'1234') ZrloBMa+B/WQm/rv3vbEw7BAnRZuAhlKuHt7/S7VfkWsB+XHSm9CiffcSqIxd02rįrom import serialization The following Python Code shows the import of an encrypted PKCS#1 key with Cryptography and P圜ryptodome: pkcs1_enc = b'''-BEGIN RSA PRIVATE KEY-ĦNRXk9JZDyV9RlaH5+HkT3PADPObPdUISVzFyHHB71vmdMoV8/Hazu2+xrZkkmPl However, you can use Cryptography ( load_pem_private_key()) or - as suggested in the comment - P圜ryptodome ( import_key()). Afaik, Python-rsa doesn't support encrypted keys, neither in PKCS#1 nor in PKCS#8 format. The exported key is a PEM encoded encrypted PKCS#1 key. However, I need to password protect these private keys.Ĭan the python rsa library ( ) support these encrypted private keys? Or should I switch to a different library? If I leave '-des3' out of the openssl command, then the Python script runs perfectly. This gives me the error: raise error.SubstrateUnderrunError('%d-octet short' % (length - len(substrate))) With open(privatekey,'r',) as privatefile:

I try to import it with the following python code, using the library rsa. Openssl.exe rsa -in exported.key -passin pass:1234 -passout pass:1234 -des3 -out myprivatekey.pem -outform pem I exported the private key from a PFX file with this command: openssl.exe pkcs12 -in 'temp.pfx' -passin pass:secret -passout pass:1234 -out exported.key 2>$null
