Hi,

I have been struggling to download Julia for a few days now (Slow South African internet connections!). The link seems to expire mid download. Eventually I got a full download (potentially). I would like to verify its integrity though.

Can any of you help me? Surprised that no checksums are provided (are they provided somewhere I don’t know about?

Here is what I tried:

$ `gpg --verify ~/Downloads/JuliaPro-0.6.4.1_build-415.sh.asc ~/Downloads/JuliaPro-0.6.4.1_build-415.sh`  
gpg: Signature made Sat 14 Jul 2018 10:17:54 AM SAST  
gpg: using RSA key 32E70AF909788F1E  
gpg: Can’t check signature: No public key

`md5sum ~/Downloads/JuliaPro-0.6.4.1_build-415.sh` 15ef711852aabf98702e62115296440e ~/Downloads/JuliaPro-0.6.4.1\_build-415.sh `sha1sum ~/Downloads/JuliaPro-0.6.4.1_build-415.sh`  
da1a2c8a4e71f5e5436f05230bbcff9c978f5b72 ~/Downloads/JuliaPro-0.6.4.1\_build-415.sh  
$ `sha256sum ~/Downloads/JuliaPro-0.6.4.1_build-415.sh`  
a760949ea9c7fabe4c75245b49893403d1e167f3533e7406b3dfe152af0be67d ~/Downloads/JuliaPro-0.6.4.1\_build-415.sh

Please could you provide me with the correct sha256sum values? Also, is the gpg command I entered above correct?

Kind regards,  
Dean

Ok, I found another forum post which helped me. I entered the command to fetch the public keys just before.

`gpg --keyserver hkp://pgp.mit.edu:80 --recv-key 0x09788F1E` gpg: key 32E70AF909788F1E: public key "Julia Computing, Inc. \<pradeep@juliacomputing.com\>" imported gpg: Total number processed: 1 gpg: imported: 1 `gpg --verify ~/Downloads/JuliaPro-0.6.4.1_build-415.sh.asc ~/Downloads/JuliaPro-0.6.4.1_build-415.sh`  
gpg: Signature made Sat 14 Jul 2018 10:17:54 AM SAST  
gpg: using RSA key 32E70AF909788F1E  
gpg: Good signature from “Julia Computing, Inc. [pradeep@juliacomputing.com](mailto:pradeep@juliacomputing.com)” [unknown]  
gpg: WARNING: This key is not certified with a trusted signature!

You can use `gpg –verify` command to verify JuliaPro Linux binaries, you have to pass `.asc` file and the JuliaPro Linux binary in question; as argument to `gpg –verify` command.

Example:-

```julia
gpg --verify JuliaPro-0.6.4.1_build-415.sh.asc JuliaPro-0.6.4.1_build-415.sh

```

You have to download .asc file separately, link to download the .asc file is provided along with JuliaPro download links. Make sure Julia Computing GPG public keys are pre-installed on your system before executing `gpg --verify`. Julia Computing GPG public keys can be found in [https://juliacomputing.com/products/faqs/juliaprofaq.html](https://juliacomputing.com/products/faqs/juliaprofaq.html) (Search for the question “Where can I find Julia Computing GPG public keys?” on the [FAQ page](https://juliacomputing.com/products/faqs/juliaprofaq.html))
