Function Documentation

apr_status_t apr_bcrypt_encode	(	const char *	pw,
		unsigned int	count,
		const unsigned char *	salt,
		apr_size_t	salt_len,
		char *	out,
		apr_size_t	out_len
	)

Encode a password using the bcrypt algorithm

Parameters

pw	The password to encode
count	The cost of the encoding, possible values are 4 to 31
salt	Pointer to binary data to be used as salt for the encoding
salt_len	The size of the salt data (must be >= 16)
out	The string to store the encoded password in
out_len	The size of the result buffer (must be >= 61)

apr_status_t apr_md5	(	unsigned char	digest[APR_MD5_DIGESTSIZE],
		const void *	input,
		apr_size_t	inputLen
	)

MD5 in one step

Parameters

digest	The final MD5 digest
input	The message block to use
inputLen	The length of the message block

apr_status_t apr_md5_encode	(	const char *	pw,
		const char *	salt,
		char *	result,
		apr_size_t	nbytes
	)

Encode a password using an MD5 algorithm

Parameters

pw	The password to encode
salt	The salt string to use for the encoding
result	The string to store the encoded password in
nbytes	The size of the result buffer

apr_status_t apr_md5_final	(	unsigned char	digest[APR_MD5_DIGESTSIZE],
		apr_md5_ctx_t *	context
	)

MD5 finalization. Ends an MD5 message-digest operation, writing the message digest and zeroing the context

Parameters

digest	The final MD5 digest
context	The MD5 content we are finalizing.

apr_status_t apr_md5_init

(

apr_md5_ctx_t *

context

)

MD5 Initialize. Begins an MD5 operation, writing a new context.

Parameters

context

The MD5 context to initialize.

apr_status_t apr_md5_set_xlate	(	apr_md5_ctx_t *	context,
		apr_xlate_t *	xlate
	)

MD5 translation setup. Provides the APR translation handle to be used for translating the content before calculating the digest.

Parameters

context	The MD5 content to set the translation for.
xlate	The translation handle to use for this MD5 context

apr_status_t apr_md5_update	(	apr_md5_ctx_t *	context,
		const void *	input,
		apr_size_t	inputLen
	)

MD5 block update operation. Continue an MD5 message-digest operation, processing another message block, and updating the context.

Parameters

context	The MD5 content to update.
input	next message block to update
inputLen	The length of the next message block

apr_status_t apr_password_validate	(	const char *	passwd,
		const char *	hash
	)

Validate hashes created by APR-supported algorithms: md5, bcrypt, and sha1. hashes created by crypt are supported only on platforms that provide crypt(3), so don't rely on that function unless you know that your application will be run only on platforms that support it. On platforms that don't support crypt(3), this falls back to a clear text string comparison.

Parameters

passwd	The password to validate
hash	The password to validate against
