pycryptodome raise valueerror rsa key format is not supported

key = RSA.importkey(pubkey) Note: if you do not add "\n" to the end of each line of your RSA key the RSA.importkey( ) will raise an error: RSA key format is not supported. It actually is part of a crypto challenge(a CTF), and I don't really know how it was prepared, but running the command openssl x509 -text -noout -inform DER -in 2048b-rsa.der prints out all the information correctly. It seems like pycrypto asn.1 implementation isn't compatible with pycryptodome? e should be chosen so that e and λ(n) are coprime. Python DES3 - 30 examples found. rsaKey = RSA.importKey(key_data, passphrase = b'jy123') 'myPrivateKey.pem' 注意配置好,如果其他程序调用这个方法,接会报错,建议设置绝对路径os.path.dirname实现 Generate an RSA key; Generate public key and private key; Encrypt data with RSA; ... argument 2 must be bytes, not bytearray? By clicking “Sign up for GitHub”, you agree to our terms of service and The RSA key to import. How was it written to a disk file? to your account, Traceback (most recent call last): I suspect that the 3rd member is the extra that rubbish that openssl asn1parse complained about. The following code encrypts a piece of data for a receiver we have the RSA public key of. return _import_keyDER (extern_key, passphrase) raise ValueError ("RSA key format is not supported") # Backward compatibility: importKey = import_key #: `Object ID`_ for the RSA encryption algorithm. I can't share the keys that are actually failing.. but I created this script to create some fresh ones... here is a more concrete example you don't have to wait for.. it seems that it doesn't use the lucas test, but simply runs the rabin_miller "more" (not sure if enough), after having done a prime sieve using the first 1k primes. Legrandin / pycryptodome. @Legrandin By the way, "RSA key format not supported" is probably too generic. with RSA.importKey on DER format key, "RSA key format is not supported" (w/test case), # just prove this isn't a completely insane key export by importing with pycrypto, 'MIIEpAIBAAKCAQEA6d-pf54zOkvLIcF1Yukmhe1Y2d0f7wg_aev_bHfm2z85yml7XWvtD6eIX5OmoLb_yDRM_1be-guX0tl9SQcJSYYsgFXh8LzxBAgPBL8NCm5BERXNIlbLDo86rPaQfoMTCSJx2hFvD_-ARjNzxuZ6_7FI88HwWibvhhtF5oM-UQ8-5X0mo1Ktgjn4Nj05lZhe-anOzU6z0Brr9WPROyu6gcVo2PBw63uW6-tIg4gvf3DMiEiYjcNbh2IpPi3G5jRJl-CRILGfR1ClrqdPi7JZQM5mhGYf2mLwkcrcf8i5usbH40HDuhoBqmHi5J1ujK8AINyd33fOELHuZDk49Ylq-wIDAQABAoIBAQCqToEzuZQ8Y20sy6AbwwSWilwlam0St8LV81ExP68RAV2oFGANi8Y5nBom33J7nkdtFwjq9-uv0jlhBZfCUillLRvC6Md7c1tfQC8PmcB5VAh11JZo5yM_GvXzdimKtxBpmnemAQQLdleGx3kL4lK3V_Zz60qHm8rYsYuZbQE4LKmArEw7--yh7f_7PD1M65DJ-zGyNbq63cYJ9tT_qgLOlY1SOPTsbodcgrEfxwD3dL276Jy4YRMSMEE5we00bTdDaPKCWOVHPB6pNzzKvLHLXpvw9DkF7zKrHa4NE2AGk-A0r_t_MSrPXfENQOhLrK4UOi-enjqeQdr68hrdVVdBAoGBAO9gKeBSpAQEhiz8BHXXFytg-lepDCwcUYIxp_8wDXH6k8DnvHm9nDaNDPz5eMfL5nyP-Mn3bw4VIlljyLw6oFwcjSnyTsHK5qL59_tw-OGjhlUPqG-rFUAO05KPOi6GxLFITgpOa3hu7rCWZoKBNuTv41gNR0nRwmbQz8_WNsN5AoGBAPodrgKeI-B0At9_VSYjbrJat_FJgwYfPUDInwJ6stCadc2UFxFkT6kXr3e_kpDikHFPadSh-H4Bu-C1EId-JBjSKPOOBZ3HwzenXxzSQdfebAMKGambgitcPBgftgSou7IDYX7vHzzHc3OlQP-Wt81Bc3gydLMKUj7KVcocFPETAoGBALSHn81wRgZJqy-t-WcuCmlKwELwWR_DU62O6ZZJlTpKsrgfjUN7Pp7djdgUBYUZQADdS9J166mBQuCLos5ioKIXXlcuSTtaXMq5Hs7hCrKRczQflPZy3pnrFKFJp6WDOkBBuamILwErGJTROQpfjRjn2luD2CnSKn0EKlYixjZxAoGAO4RSgwb0jJWulVZsga3OypwxxzXx-sP2RHM4-1MNN_x5adkCgD35gshDFeC9VMLFEmGOUm3Ufs-U0IzliQhoOIvR-Nrj1T7S4mxugqI5zs97rmF559U8bWr-VdM98e_g8iRBz_3A1iqz-2HojKllxW78ti5zfKNJHO3y6iwyg4cCgYBqhiV3nHr6oWxhdxUjBkAniY581MrrnMcwVgkj2XIB6-1Vkckruk0XbOfJUJTRTETb6S9sFctyJm5QPVKEjx5WA1jtSw6qIY-9lN9WGkI_brkyo42fo7k9-aQhOkWZMYj2DxS1h641bCGiONg0ET3jMnrzq4gf-jl6sq50wTqBFg=='. Think of RSA, Diffie-Hellman, ECC, and others as protocols or languages. The text was updated successfully, but these errors were encountered: How was this DER file generated? Or, at the low-level routines, print error messages with more detail as to what is going wrong. It is more formally called RSASSA-PKCS1-v1_5 in Section 8.2 of RFC8017.. when trying to import those keys. I tested this with openssl and it says the number is prime: fwiw: this fails due to the choice of 10 as the maximal choice of number of D "alternates" in Cryto/Math/Primality.py:lucas_test() .. alternate(). Then, process the message with its update() method. Parameters: key (RSA key object) – The key object to use to encrypt or decrypt the message.Decryption is only possible with a private RSA key. i have verified that if this lucas-test check is caused to pass by checking within the first 13, then the full lucas_test() of this candidate results in 1. as written, this is consistent, but it is unable to function when the loaded key is not validated according to this slower/(more-thorough?) Thanks for looking into this! domain (tuple) – The DSA domain parameters p, q and g as a list of 3 integers. I copied the files from a CTF and this was the output raise ValueError("RSA key format is not supported") 2048b-rsa.zip. Note 2: I used "\" to indicate that statement is continued on the next line. privacy statement. These are the top rated real world Python examples of CryptoCipher.DES3 extracted from open source projects. The modules are packaged using the Distutils, so you can simply run “python setup.py build” to build the package, and “python setup.py install” to install it. Pycryptodome is now free of CPython extensions. The format to use for wrapping the key: ‘DER’.
