Detailed Description

Header file for the MD5 cryptographic hash function.

This header file defines the interface for computing the MD5 hash, a widely-used cryptographic hash algorithm that produces a 128-bit (16-byte) digest. The MD5 algorithm processes data in 512-bit blocks and is commonly used for checksum calculations and data integrity verification.

Note

MD5 is considered cryptographically broken and unsuitable for secure applications. It is provided primarily for legacy support and non-critical usage scenarios.

Function Documentation

ha_md5_final()

HA_PUBFUN void ha_md5_final	(	ha_md5_context *	ctx,
		ha_digest_t	digest )

Finalizes the MD5 computation and produces the hash digest.

This function finals the MD5 hash calculation and outputs the resulting digest into the provided buffer.

Parameters

ctx	Pointer to the MD5 context structure.
digest	Pointer to the output buffer to store the final MD5 digest (16 bytes).

ha_md5_hash()

HA_PUBFUN void ha_md5_hash	(	ha_inbuf_t	data,
		size_t	len,
		ha_digest_t	digest )

Computes the MD5 hash in a one-shot operation.

This function computes the MD5 hash of the provided data in a single call. It initializes, updates, and finals the MD5 computation internally.

Parameters

data	Pointer to the input data to process.
len	Length of the input data in bytes.
digest	Pointer to the output buffer to store the final MD5 digest (16 bytes).

ha_md5_init()

HA_PUBFUN void ha_md5_init

(

ha_md5_context *

ctx

)

Initializes the MD5 context.

This function initializes the MD5 context to start a new hash computation.

Parameters

ctx	Pointer to the MD5 context structure to initialize.

ha_md5_update()

HA_PUBFUN void ha_md5_update	(	ha_md5_context *	ctx,
		ha_inbuf_t	data,
		size_t	len )

Updates the MD5 context with new data.

This function processes the provided data and updates the MD5 context state.

Parameters

ctx	Pointer to the MD5 context structure.
data	Pointer to the input data to process.
len	Length of the input data in bytes.
