| AES-128 key for Dark Souls Remastered. | |

Encryption keys. All of these ship inside the games; none is a secret.

| sl2.keys.DS2_VANILLA_KEY = bytes.fromhex("B7FD463E4A9C1102DF1739E5F3B2A50F") |
AES-128 key for VANILLA Dark Souls II (the DX9 original, DARKSII0000.sl2), which is a different key from Scholar of the First Sin above.
From TKGP's SoulsFormats SFUtil.GetDS2SaveKey(). Verified on a real DARKSII0000.sl2: the character block decrypts to entropy 2.8 (the SOTFS key gives 7.99 noise), the name reads out, and every SOTFS field offset lands — see DS2_VANILLA_LAYOUT below.

AES-128 key for Elden Ring Nightreign.
From alfizari/Elden-Ring-Nightreign-Save-Editor (MIT), where it is misleadingly named DS2_KEY — it is not Dark Souls II's, which is DS2_KEY above and a different sixteen bytes. It does not need to be taken on trust: every Nightreign entry stores an MD5 of its own plaintext, and with this key all fourteen entries of the test save hash to the value they carry. A wrong key cannot do that.
