Detailed Description

Returns the RIPEMD-160 digest of the SHA256 hash of the message.

This operation is used to compute the 160-bit identifier representing a Ripple account, from a message. Typically the message is the public key of the account - which is not stored in the account root.

The same computation is used regardless of the cryptographic scheme implied by the public key. For example, the public key may be an ed25519 public key or a secp256k1 public key. Support for new cryptographic systems may be added, using the same formula for calculating the account identifier.

Meets the requirements of Hasher (in hash_append)
