-C API for pgcrypto
-==================
-
-
-UN*X crypt()
-============
-
-#include <px-crypt.h>
-
-char *
-px_crypt(const char *psw, const char *salt, char *buf, unsigned buflen);
-
-	returns buf or NULL for error.
-
-unsigned px_gen_salt(const char *salt_type, char *dst, int rounds);
-
-	returns salt size.  dst should be PX_MAX_SALT_LEN bytes.
-	'rounds' is algorithm specific.  0 means default for
-	that algorithm.
-
-Random
-======
-
-int px_get_random_bytes(uint8 *dst, int num)
-
-
-Crypto "objects"
-================
-
-PX_MD      - Message digest
-PX_HMAC    - HMAC (Hash MAC)
-PX_Cipher  - cipher+mode: provided by libs
-PX_Combo   - higher-level encryption -> padding, [MD]
-
-Objects are activated with following functions:
-
-int px_find_digest(const char *name, PX_MD **res);
-int px_find_hmac(const char *name, PX_HMAC **res);
-int px_find_cipher(const char *name, PX_Cipher **res);
-int px_find_combo(const char *name, PX_Combo **res);
-
-	returns 0 on success, < 0 on error.  If successful,
-	*res contains pointer to new object.
-
-Message Digest
-==============
-
-uint px_md_result_size(PX_MD *md)
-
-	returns final result size in bytes
-
-void px_md_reset(PX_MD *md)
-
-	resets md to clean state
-
-uint px_md_block_size(PX_MD *md)
-
-	return algorithm block size in bytes
-
-void px_md_update(PX_MD *md, const uint8 *data, uint dlen)
-
-	updates hash state with new data
-
-void px_md_finish(PX_MD *md, uint8 *buf)
-
-	puts final hash state into buf.  buf should have room
-	for px_md_result_size() bytes.
-
-void px_md_free(PX_MD *md)
-
-	frees resources.
-
-HMAC (Hash Message Authentication Code)
-=======================================
-
-int px_hmac_init(PX_HMAC *hmac, const uint8 *key, uint klen)
-
-	initalized hmac state with key.
-
-uint px_hmac_result_size(PX_HMAC *md)
-
-	returns final result size in bytes
-
-void px_hmac_reset(PX_HMAC *md)
-
-	resets md to state after _init()
-
-uint px_hmac_block_size(PX_HMAC *md)
-
-	return algorithm block size in bytes
-
-void px_hmac_update(PX_HMAC *md, const uint8 *data, uint dlen)
-
-	updates hash state with new data
-
-void px_hmac_finish(PX_HMAC *md, uint8 *buf)
-
-	puts final hash state into buf.  buf should have room
-	for px_hmac_result_size() bytes.
-
-void px_hmac_free(PX_HMAC *md)
-
-	frees resources.
-
-
-Cipher
-======
-
-uint px_cipher_key_size(PX_Cipher *c)
-
-	returns max key size in bytes
-
-uint px_cipher_block_size(PX_Cipher *c)
-
-	returns cipher+mode block size in bytes.  So blowfish
-	in CFB mode should return 1.
-
-uint px_cipher_iv_size(PX_Cipher *c)
-
-	returns IV size in bytes.
-
-int px_cipher_init(PX_Cipher *c, uint8 *key, uint klen, uint8 *iv)
-
-	initializes cipher with supplied key and iv.
-
-int px_cipher_encrypt(PX_Cipher *c, uint8 *data, uint dlen, uint8 *res)
-
-	encrypts data.  res must have room for dlen bytes.
-	data must be multiple of px_cipher_block_size().
-
-int px_cipher_decrypt(PX_Cipher *c, uint8 *data, uint dlen, uint8 *res)
-
-	decrypts data.  res must have room for dlen bytes.
-
-void px_cipher_free(PX_Cipher *c)
-
-	frees resources assiocated.
-
-PX_Combo
-========
-
-uint px_combo_encrypt_len(PX_Combo *c, uint dlen)
-
-	calculates max result length for dlen of data.
-
-uint px_combo_decrypt_len(PX_Combo *c, uint dlen)
-
-	calculates result length for dlen of data.
-
-int px_combo_init(PX_Combo *c, uint8 *key, uint klen, uint8 *iv, uint ivlen)
-
-	initializes c with key and iv.  If cipher uses fixed length keys,
-	key will be padded with zeroes to needed length.
-
-int px_combo_encrypt(PX_Combo *c, uint8 *data, uint dlen, uint8 *res, uint rlen)
-
-int px_combo_decrypt(PX_Combo *c, uint8 *data, uint dlen, uint8 *res, uint rlen)
-
-void px_combo_free(PX_Combo *c)
-
-	frees resources assiocated.
