I cannot reproduce this with libgcrypt 1.8.7-3 from Debian. Which version are you using? Does it happen every time? |
|
|
I used 1.9.2. Yes, it does happen everytime. It is this error: http://gnupg.10057.n7.nabble.com/Ohhhh-jeeee-mulm-25519-different-sizes-td56665.html |
|
|
This seems to be an issue with 1.9.X. Independently verified by t3ss (1.8.2) and ch3 (1.9.2) |

I disabled the build and test for crypto_ecc_dlog as well as the whole scalarproduct subsystem if we detect libgcrypt 1.9. Note that this "kind of" puts scalarproduct on a depecation timer as eventually systems will no longer ship 1.8. Keeping this bug open. Target version 0.15.0 due to likely breakage of API on fix. A libsodium implementation for ecc_dlog is in https://git.gnunet.org/gnunet.git/log/?h=dev/schanzen/crypto_dlog_sodium |
|
|
I have now gotten the util ECC dlog tests to pass and the scalarproduct code to compile. However, the scalarproduct test still fails. Likely somewhere I am not correctly understanding/using some libsodium operation, OR (less likely) there was a "simple" bug in translation of the code :-(. Anyway, the next thing to fix is definitively test_ecc_scalarproduct, and once that passes, we should be able to get the rest to pass by apply the same fix to the Alice/Bob logic. |

|
Code now works in the branch, ready to merge. |
