pycryptodome 3.5.1 stop working after installing python "requests" packages

[Herman Wijaya]

My pycryptodome 3.5.1 stop working after installing the following python "requests" packages:

    asn1crypto:      0.24.0-py36_0

    ca-certificates: 2017.08.26-h94faf87_0

    cffi:            1.11.5-py36h945400d_0

    chardet:         3.0.4-py36h420ce6e_1

    cryptography:    2.1.4-py36he1d7878_0

    idna:            2.6-py36h148d497_1

    openssl:         1.0.2n-h74b6da3_0

    pycparser:       2.18-py36hd053e01_1

    pyopenssl:       17.5.0-py36h5b7d817_0

    pysocks:         1.6.8-py36_0

    requests:        2.18.4-py36h4371aae_1

    six:             1.11.0-py36h4db2310_1

    urllib3:         1.22-py36h276f60a_0

    win_inet_pton:   1.0.1-py36he67d7fd_1

Any solutions? I've rolled-back my environment and it works again normally. Thanks.

Hi Herman,

That's bizarre. Could you share what error or exception you see exactly?

It could be that one of those packages pulls the old pycrypto, but
that does not seem the case to me.

Hi Helder,

Good to hear from you!

After I installed the "requests" and its dependency packages, I was trying to use run my script which uses the RSA key generator (RSA.generate(2048)) from the Cryptodome.PublicKey. It throwed this error:

gnu mp: cannot allocate memory (old_size=8 new_size=187904819464)

Similarly, when I tried to switch using the ECC key generator (ECC.generate(curve="P-256") for DSS, it also didn't work. Unfortunately I didn't capture the error for this.

I used conda package manager and able to roll-back to the previous environment state. Upon rolling-back to the earlier state, all the above calls work perfectly fine.

Hi Herman,

If you don't mind, could you answer these 3 questions:
1) Which OS are you using (Linux/Windows 7/Mac, 32/64 bits)?
2) To which version have you rolled back?
3) Are you using package pycryptodome (Crypto.PublicKey) or
pycryptodomex (Cryptodome.PublicKey)?

Thanks,

H.E.

Hi Helder,

1. I'm using Windows 10 64-bit

2. I'm using Anaconda distribution and rolled back my earlier Python environment by removing the "requests" package and its dependancies as the following:

>     win_inet_pton:   1.0.1-py36he67d7fd_1

3. I'm using pycryptodomex package (Cryptodome.PublicKey)

Many thanks.
