Function Documentation

const char* encrypt_clear	(	const char *	pass,
			...
	)

Using cleartext password.

This function returns only the cleartext password.

Parameters:

pass

The user password.

Return values:

	const	char* The encrypted password.
	NULL	if something went wrong.

const char* encrypt_crypt	(	const char *	pass,
			...
	)

String encoding function.

This function first generate a t9 hash and encrypt this hash with md5.

Parameters:

pass

The user password. The second parameter is the salt (const char*) Parameter which will be used to generate a hash. The third parameter is the options (modopt_t) Parameter which contains the encryption type.

Return values:

	const	char* The encrypted password.
	NULL	if something went wrong.

const char* encrypt_md5	(	const char *	pass,
			...
	)

Encrypt a password using md5-algorithm.

This function generates a md5 hash from pass.

Parameters:

pass

The user password.

Return values:

	const	char* The encrypted password.
	NULL	if something went wrong.

const char* encrypt_sha1	(	const char *	pass,
			...
	)

Encrypt a password using sha1-algorithm.

This function generates a sha1 hash from pass.

Parameters:

pass

The user password.

Return values:

	const	char* The encrypted password.
	NULL	if something went wrong.

const char* encrypt_t9	(	const char *	pass,
			...
	)

Encrypt a password using t9-algorithm.

This function generates a t9 hash from pass.

Parameters:

pass

The user password.

Return values:

	const	char* The encrypted password.
	NULL	if something went wrong.

const char* encrypt_t9_md5	(	const char *	pass,
			...
	)

Combining t9 and md5 encryption.

This function first generate a t9 hash and encrypt this hash with md5.

Parameters:

pass

The user password.

Return values:

	const	char* The encrypted password.
	NULL	if something went wrong.

const char* password_encrypt	(	const char *	pass,
		const char *	salt,
		const modopt_t *	options
	)

Encrypt a password.

This functinos takes the userpassword and encrypt it to the type specified in the modopt_t-struct options respectively the salt parameter.

Parameters:

	pass	The user password.
	salt	If you want to hashify your password with additional information which will be computed in in the new hash.
	options	A modopt_t struct, which contains the hashtype.

Return values:

	char*	The encrypted password.
	NULL	if something went wrong.
