Use `crypto/sha256` (#29386) Go 1.21 improved the performance of `crypto/sha256`. It's now similar to `minio/sha256-simd`, so we should just use the standard libs. https://go.dev/doc/go1.21#crypto/sha256 https://go-review.googlesource.com/c/go/+/408795 https://github.com/multiformats/go-multihash/pull/173 9 months ago			`"crypto/sha256"`
Replace fmt.Sprintf with hex.EncodeToString (#21960) `hex.EncodeToString` has better performance than `fmt.Sprintf("%x", []byte)`, we should use it as much as possible. I'm not an extreme fan of performance, so I think there are some exceptions: - `fmt.Sprintf("%x", func(...)[N]byte())` - We can't slice the function return value directly, and it's not worth adding lines. ```diff func A()[20]byte { ... } - a := fmt.Sprintf("%x", A()) - a := hex.EncodeToString(A()[:]) // invalid + tmp := A() + a := hex.EncodeToString(tmp[:]) ``` - `fmt.Sprintf("%X", []byte)` - `strings.ToUpper(hex.EncodeToString(bytes))` has even worse performance. 2 years ago			`"encoding/hex"`
