}
Expand description

Operations providing cryptographic functionality.

Variants§

§

Sha256

0x50: SHA2

Produce a SHA 256 hash from the specified data.

Hashes are byte aligned so length is number of bytes not number of words.

§Stack Input

[data, data_len]

§Stack Output

[hash_w0, hash_w1, hash_w2, hash_w3]

§Panics
  • data_len * 8 is longer than the data.
§

VerifyEd25519

0x51: VRFYED

Validate an Ed25519 signature against a public key.

Data is byte aligned so length is number of bytes not number of words.

§Stack Input

[data, data_len, sig_w0, sig_w1, sig_w2, sig_w3, sig_w4, sig_w5, sig_w6, sig_w7, key_w0, key_w1, key_w2, key_w3]

§Stack Output

[bool]

§

RecoverSecp256k1

0x52: RSECP

Recover the public key from a secp256k1 signature.

If the signature is invalid, the operation will return all zeros.

§Stack Input

[hash_0, hash_1, hash_2, hash_3, sig_w0, sig_w1, sig_w2, sig_w3, sig_w4, sig_w5, sig_w6, sig_w7, sig_8]

§Stack Output

[pub_key_w0, pub_key_w1, pub_key_w2, pub_key_w3, pub_key_4]
