Package ethdigest provides tools for working with eth-digests, for the Go programming language.

The eth-digest (also called an ethereum-digest, evm-digest, and mistakenly also called an ethereum-hash or evm-hash) is a 32-byte digest — and is commonly used by EVM based networks, as well as other places.

ethdigest.Digest is meant to be a replacement for go-ethereum/common.Hash from the official Ethereum golang package.

Here is an example of loading an ethdigest.Digest from a hexadecimal-literal stored in a Go string:

digest, err := ethdigest.ParseString("0x5aAeb6053F3E94C9b9A09f33669435E7Ef1BeAed0f1e2d3c4b5a69788796a5b4")

Here is an example of loading an ethdigest.Digest from a hexadecimal-literal stored in a Go []byte:

var bytes []byte = []byte("0x5aAeb6053F3E94C9b9A09f33669435E7Ef1BeAed0f1e2d3c4b5a69788796a5b4")

digest, err := ethdigest.Parse(bytes)

Here is an example of loading an ethdigest.Digest from a Go [20]byte:

digest := ethdigest.Something( [32]{0x5a,0xAe,0xb6,0x05,0x3F,0x3E,0x94,0xC9,0xb9,0xA0,0x9f,0x33,0x66,0x94,0x35,0xE7,0xEf,0x1B,0xeA,0xed,0x0f,0x1e,0x2d,0x3c,0x4b,0x5a,0x69,0x78,0x87,0x96,0xa5,0xb4} )

Here is an example of loading an ethdigest.Digest from a Go *big.Int:

var bigint *big.Int = // ...

digest := ethdigest.BigInt(bigint)
