## sha256 Implementation
|
|
|
|
This is needed for hashing to/from big endian, possibly with leading and trailing 0s.
|
|
|
|
|
|
|
|
We use 20 byte value `0x7f5a.997b.83f5.1f79.3b89.10be.9950.8b00.a136.f900`
|
|
|
|
|
|
|
|
### JS Reference Values
|
|
|
|
```
|
|
|
|
val = "7f5a997b83f51f793b8910be99508b00a136f900";
|
|
|
|
b = Buffer.from(val, "hex");
|
|
|
|
createHash('sha256').update(b).digest();
|
|
|
|
// yields: <Buffer 4d 9a 8e 9b 96 6c f8 3a 69 5c 60 7b c3 23 74 a0 d2 70 35 aa 52 a0 b6 73 8d c4 73 fe 95 c6 8f b3>
|
|
|
|
|
|
|
|
val2 = "007f5a997b83f51f793b8910be99508b00a136f900";
|
|
|
|
b2 = Buffer.from(val2, "hex");
|
|
|
|
createHash('sha256').update(b2).digest();
|
|
|
|
// yields: <Buffer 66 ee cb 4f b5 0e 9d 93 f8 5e 78 69 6a 34 09 7a b8 59 fb c9 b7 f6 f0 87 33 29 42 3b 5f dd 80 72>
|
|
|
|
```
|
|
|
|
|
|
|
|
In the Hoon version, we indicate leading zeros by increasing the byte count, rather than with a string
|
|
|
|
```

## Byte Buffers
|
|
|
|
Makes it easy to concatenate hex sequences with leading 0s, and then convert them back to bytes for hashing.

### BTC pubkey -> address hashing (Hash-160)
|
2020-10-04 16:07:07 +03:00
|
|
|
Uses the example data here:
|
|
|
|

|
|
|
|
|
2020-10-05 10:55:10 +03:00
|
|
|
That one starts with pubkey below. The following runs it through sha256 and ripemd160 to get Hash-160:
|
2020-10-04 17:16:35 +03:00
|
|
|
```

|
|
|
```
|
|
|
|
|
2020-10-04 16:07:07 +03:00

Use `@uc` to make the Hash-160 into a BTC P2PKH address
|

|
```
