Who here has a Youtube-DL compile for WinXP?

They are actually and always have been.
I don't update the upstream script anymore, but all that I locally changed was "openssl-3.3.1" to "openssl-3.6.1".

this doesn't add up at all with my findings

You're right. I take it back what I said earlier. I have actually changed the build_openssl3() function locally to automate the process of creating the shared- as well as the static-release. And in the process I forgot to strip both dlls. The filesizes are now identical to what you ended up with. I re-uploaded 'openssl-3.6.1-win32-shared-dev-xpmod-sse.7z'.

Many thanks for your follow-up , which actually sets the record straight  ; and thanks for the re-upload  !

Best regards.

Where are these OpenSSL DLLs usable in apart from a YouTube downloader? Legacy applications that I have all depend on libeay32 and ssleay32. And do they support new algorithms to justify their much bigger size?

With version 3.6.0 new functionality has been added (3.6.1 is mainly a security release):

Major changes between OpenSSL 3.5 and OpenSSL 3.6.0 [1 Oct 2025]

OpenSSL 3.6.0 is a feature release adding significant new functionality to OpenSSL.

This release incorporates the following potentially significant or incompatible changes:

• Added NIST security categories for PKEY objects.

• Added support for EVP_SKEY opaque symmetric key objects to the key derivation and key exchange provider methods. Added EVP_KDF_CTX_set_SKEY(), EVP_KDF_derive_SKEY(), and EVP_PKEY_derive_SKEY() functions.

• Added LMS signature verification support as per SP 800-208. This support is present in both the FIPS and default providers.

• An ANSI-C toolchain is no longer sufficient for building OpenSSL. The code should be built using compilers supporting C-99 features.

• Support for the VxWorks platforms has been removed.

• Added an openssl configutl utility for processing the OpenSSL configuration file and dumping the equal configuration file.

• Added support for FIPS 186-5 deterministic ECDSA signature generation to the FIPS provider.

• Deprecated EVP_PKEY_ASN1_METHOD-related functions.

@VistaLover

I have uploaded an updated Vista+ compatible PyInstaller here.

Could you test if the yt-dlp built with it works well on your Vista system?
