Typedef Documentation

fr_md5_ctx_alloc_t

typedef fr_md5_ctx_t *(* fr_md5_ctx_alloc_t) (void)

Allocation function for MD5 digest context.

Returns

• An MD5 ctx.
• NULL if out of memory.

Definition at line 53 of file md5.h.

fr_md5_ctx_copy_t

typedef void(* fr_md5_ctx_copy_t) (fr_md5_ctx_t *dst, fr_md5_ctx_t const *src)

Copy the contents of a ctx.

Parameters

[in]	dst	Where to copy the context to.
[in]	src	Where to copy the context from.

Definition at line 44 of file md5.h.

fr_md5_ctx_free_t

typedef void(* fr_md5_ctx_free_t) (fr_md5_ctx_t **ctx)

Free function for MD5 digest ctx.

Parameters

[in]

ctx

MD5 ctx to free. If the shared ctx is passed in then the ctx is reset but not freed.

Definition at line 61 of file md5.h.

fr_md5_ctx_reset_t

typedef void(* fr_md5_ctx_reset_t) (fr_md5_ctx_t *ctx)

Reset the ctx to allow reuse.

Parameters

[in]

ctx

To reuse.

Definition at line 36 of file md5.h.

fr_md5_ctx_t

typedef void fr_md5_ctx_t

Definition at line 28 of file md5.h.

fr_md5_final_t

typedef void(* fr_md5_final_t) (uint8_t out[static MD5_DIGEST_LENGTH], fr_md5_ctx_t *ctx)

Finalise the ctx, producing the digest.

Parameters

[out]	out	The MD5 digest.
[in]	ctx	To finalise.

Definition at line 78 of file md5.h.

fr_md5_update_t

typedef void(* fr_md5_update_t) (fr_md5_ctx_t *ctx, uint8_t const *in, size_t inlen)

Ingest plaintext into the digest.

Parameters

[in]	ctx	To ingest data into.
[in]	in	Data to ingest.
[in]	inlen	Length of data to ingest.

Definition at line 70 of file md5.h.

Function Documentation

int fr_hmac_md5	(	uint8_t	digest[static MD5_DIGEST_LENGTH],
		uint8_t const *	in,
		size_t	inlen,
		uint8_t const *	key,
		size_t	key_len
