Hashing string with sha-384 always returns an empty ArrayBuffer

Describe the bug When hashing something with sha-384, the await subtle.digest(“sha-384”, stringToHash) alway results in an empty ArrayBuffer. Steps to Reproduce

1. Create a file with the example usage from std@0.112.0/crypto
2. Replace the "hello world" string with new TextEncoder().encode("hello world") (because the function does not take strings anymore)
3. Run the Script

Expected behavior

Something like

Check file:///PathToFile/cryptoTest.ts
Uint8Array(48) [
  253, 189, 142, 117, 166, 127,  41, 247,   1,
  164, 224,  64,  56,  94,  46,  35, 152,  99,
    3, 234,  16,  35, 146,  17, 175, 144, 127,
  203, 184,  53, 120, 179, 228,  23, 203, 113,
  206, 100, 110, 253,   8,  25, 221, 140,   8,
  141, 225, 189
]
Uint8Array(32) [
  215,  73, 129, 239, 167,  10,  12,
  136,  11, 141, 140,  25, 133, 208,
  117, 219, 203, 246, 121, 185, 154,
   95, 153,  20, 229, 170, 249, 107,
  131,  26, 158,  36
]

instead of

Check file:///PathToFile/cryptoTest.ts
ArrayBuffer {}
Uint8Array(32) [
  215,  73, 129, 239, 167,  10,  12,
  136,  11, 141, 140,  25, 133, 208,
  117, 219, 203, 246, 121, 185, 154,
   95, 153,  20, 229, 170, 249, 107,
  131,  26, 158,  36
]

Environment

• OS: Windows 11 (AMD64) as well as Debian (aarch64)
• deno version: 1.15.2 (release, x86_64-pc-windows-msvc) as well as 1.15.2 (debug, aarch64-unknown-linux-gnu)
• std version: both 0.112.0 (Most recent one at time of posting) and the main branch of this repo (Last Commit before my testing)

@lmx-Hexagram This is not an issue with std/crypto. Deno’s console implementation chose not print the byteLength for ArrayBuffers. You can get the underlying bytes by putting into a view (a TypedArray)

Anyways, https://github.com/denoland/deno_std/pull/1515 already fixed the original issue by always returning an ArrayBuffer (in accordance with WebCrypto).

Apparently converting the empty ArrayBuffer to a UInt8Array with new Uint8Array(await crypto.subtle.digest("SHA-384", new TextEncoder().encode("hello world"))) returns the proper Values.
