NAME

6       b2i_PVK_bio, b2i_PVK_bio_ex, i2b_PVK_bio, i2b_PVK_bio_ex - Decode and
7       encode functions for reading and writing MSBLOB format private keys

SYNOPSIS

10        #include <openssl/pem.h>
11
12        EVP_PKEY *b2i_PVK_bio(BIO *in, pem_password_cb *cb, void *u);
13        EVP_PKEY *b2i_PVK_bio_ex(BIO *in, pem_password_cb *cb, void *u,
14                                 OSSL_LIB_CTX *libctx, const char *propq);
15        int i2b_PVK_bio(BIO *out, const EVP_PKEY *pk, int enclevel,
16                        pem_password_cb *cb, void *u);
17        int i2b_PVK_bio_ex(BIO *out, const EVP_PKEY *pk, int enclevel,
18                           pem_password_cb *cb, void *u,

DESCRIPTION

22       b2i_PVK_bio_ex() decodes a private key of MSBLOB format read from a
23       BIO. It attempts to automatically determine the key type. If the key is
24       encrypted then cb is called with the user data u in order to obtain a
25       password to decrypt the key. The supplied library context libctx and
26       property query string propq are used in any decrypt operation.
27
28       b2i_PVK_bio() does the same as b2i_PVK_bio_ex() except that the default
29       library context and property query string are used.
30
31       i2b_PVK_bio_ex() encodes pk using MSBLOB format. If enclevel is 1 then
32       a password obtained via pem_password_cb is used to encrypt the private
33       key.  If enclevel is 0 then no encryption is applied. The user data in
34       u is passed to the password callback. The supplied library context
35       libctx and property query string propq are used in any decrypt
36       operation.
37
38       i2b_PVK_bio() does the same as i2b_PVK_bio_ex() except that the default
39       library context and property query string are used.

RETURN VALUES

42       The b2i_PVK_bio() and b2i_PVK_bio_ex() functions return a valid EVP_KEY
43       structure or NULL if an error occurs. The error code can be obtained by
44       calling ERR_get_error(3).
45
46       i2b_PVK_bio() and i2b_PVK_bio_ex() return the number of bytes
47       successfully encoded or a negative value if an error occurs. The error
48       code can be obtained by calling ERR_get_error(3).
