importaddress (and possibly other legacy-only wallet functions), when used on a descriptor wallet, return a fairly nondescript error:

$ ./bitcoin-cli -regtest importaddress test
error code: -4
error message:
This type of wallet does not support this command

The RPC help of importaddress doesn't mention nor further explain this incompatibility, nor what alternative to use inste

when calling EVP_PKCS82PKEY or d2i_PKCS8PrivateKey ...
added PBE algorithm call app is crash. After adding the new PBE algorithm.

because dynamic memory allocation in OPENSSL_malloc is return garbage value.
"pbe_tmp->keygen_ex" not initialized function pointer. so EVP_PBE_CipherInit_ex alway call
invalid pointer function keygen_ex.

if (keygen_ex != NULL) // always true

Hey Hackers of this spoopy month! 👻
Welcome to the Ciphey repo(s)!
This issue requires you to add a decoder.

This wiki section walks you through EVERYTHING you need to know, and we've added some more links at the bottom of this issue to detail more about the decoder.

Background

Postgresql backend would allow for very fast data access, by directly querying the database with your coding language of choice and a DB driver, instead of using lnd as intermediary with gRPC. This will need previous knowledge of things to look for in the database.
I did open the DB with an explorer, and the contents are... overwhelming to say the least.
I personally have no ad

Problem:

A common pattern is:

GUARD(s2n_stuffer_skip_write(stuffer, bytes_to_write));
uint8_t* ptr = suffer->blob.data + stuffer->write_cursor - bytes_to_write;

which could be simplified.

Solution:

*ptr could be an *out parameter to s2n_stuffer_skip_write

  • Does this change what S2N sends over the wire? No.
  • Does this change any public APIs? No.

HElib is an open-source software library that implements homomorphic encryption. It supports the BGV scheme with bootstrapping and the Approximate Number CKKS scheme. HElib also includes optimizations for efficient homomorphic evaluation, focusing on effective use of ciphertext packing techniques and on the Gentry-Halevi-Smart optimizations.
