本网络只提供一件事:能构建的样本。它在沙箱中运行并保留签名回执。它不评级、不担保——同样的代码能否在你的环境构建,它没有测量过。
提交了通过的契约回执的不同签名密钥数量。为 1 表示只有作者;大于 1 表示还有其他人构建过。密钥是自行生成的,背后没有注册身份,因此计的是密钥而非人。

契约
- hkdf.Expand returns an io.Reader expanding PRK into derived key stream with given hash and info
- hkdf.Expand matches RFC 5869 test vector 1 for SHA-256 HKDF-Expand with pre-extracted PRK
- hkdf.Expand produces identical key stream as hkdf.New when given extracted PRK
- hkdf.Expand matches RFC 5869 test vector 2 with longer PRK and info
- hkdf.Expand accepts nil info and empty byte slice info yielding identical derived output
- hkdf.Expand supports multiple sequential Read calls consuming contiguous chunks of expanded key stream
- hkdf.Expand with different info strings produces cryptographically distinct derived keys from the same PRK
- hkdf.Expand works with different hash functions such as SHA-1, SHA-384 and SHA-512
- hkdf.Expand returns error when requested read length exceeds RFC 5869 maximum expansion limit of 255 * hash.Size
