§Hash functions

This module defines jets for computing SHA-256 hashes. Be aware that SHA-256 padding isn’t provided and messages should be manually padded.

sha_256_block: Update the given 256-bit midstate by running the SHA256 block compression function, using the given 512-bit block.
sha_256_ctx_8_add_1: Add 1 byte to the SHA256 hash engine.
sha_256_ctx_8_add_2: Add 2 bytes to the SHA256 hash engine.
sha_256_ctx_8_add_4: Add 4 bytes to the SHA256 hash engine.
sha_256_ctx_8_add_8: Add 8 bytes to the SHA256 hash engine.
sha_256_ctx_8_add_16: Add 16 bytes to the SHA256 hash engine.
sha_256_ctx_8_add_32: Add 32 bytes to the SHA256 hash engine.
sha_256_ctx_8_add_64: Add 64 bytes to the SHA256 hash engine.
sha_256_ctx_8_add_128: Add 128 bytes to the SHA256 hash engine.
sha_256_ctx_8_add_256: Add 256 bytes to the SHA256 hash engine.
sha_256_ctx_8_add_512: Add 512 bytes to the SHA256 hash engine.
sha_256_ctx_8_add_buffer_511: Add a list of less than 512 bytes to the SHA256 hash engine.
sha_256_ctx_8_finalize: Produce a hash from the current state of the SHA256 hash engine.
sha_256_ctx_8_init: Initialize a default SHA256 hash engine.
sha_256_iv: Return the SHA256 initial value.
