マクロ定義

#define APR_SHA1_DIGESTSIZE   20

size of the SHA1 DIGEST

#define APR_SHA1PW_ID   "{SHA}"

Define the Magic String prefix that identifies a password as being hashed using our algorithm.

#define APR_SHA1PW_IDLEN   5

length of the SHA Password

関数

void apr_sha1_base64	(	const char *	clear,
		int	len,
		char *	out
	)

Provide a means to SHA1 crypt/encode a plaintext password in a way which makes password file compatible with those commonly use in netscape web and ldap installations.

引数:

	clear	The plaintext password
	len	The length of the plaintext password
	out	The encrypted/encoded password

覚え書き:

SHA1 support is useful for migration purposes, but is less secure than Apache's password format, since Apache's (MD5) password format uses a random eight character salt to generate one of many possible hashes for the same password. Netscape uses plain SHA1 without a salt, so the same password will always generate the same hash, making it easier to break since the search space is smaller.

void apr_sha1_final	(	unsigned char	digest[APR_SHA1_DIGESTSIZE],
		apr_sha1_ctx_t *	context
	)

Finish computing the SHA digest

引数:

	digest	the output buffer in which to store the digest
	context	The context to finalize

void apr_sha1_init

(

apr_sha1_ctx_t *

context

)

Initialize the SHA digest

引数:

context

The SHA context to initialize

void apr_sha1_update	(	apr_sha1_ctx_t *	context,
		const char *	input,
		unsigned int	inputLen
	)

Update the SHA digest

引数:

	context	The SHA1 context to update
	input	The buffer to add to the SHA digest
	inputLen	The length of the input buffer

void apr_sha1_update_binary	(	apr_sha1_ctx_t *	context,
		const unsigned char *	input,
		unsigned int	inputLen
	)

Update the SHA digest with binary data

引数:

	context	The SHA1 context to update
	input	The buffer to add to the SHA digest
	inputLen	The length of the input buffer
