WebSep 24, 2024 · To generate a signature, sign the string with your private key using a ES256 algorithm (also known as ECDSA using P-256 curve and SHA-256 hash algorithm). The signature must be Base64 URL-encoded. I don't need to decrypt anything, I just need to sign the string and add it to the end of my request URL. So I don't think I need anything … Web这种情况就是因为没有使用正确的VAE。. 什么是VAE?. VAE 的全称是Variational Auto-Encoder,翻译过来是变分自动编码器,本质上是一种训练模型,Stable Diffusion里的VAE主要是模型作者将训练好的模型“解压”的解码工具。. 在C站下载模型,需要特定VAE的情况 …
