.. \*(C` and \*(C' are quotes in nroff, nothing in troff, for use with C<>.
. ds C` "" . ds C' "" 'br\} . ds C` . ds C' 'br\}
Escape single quotes in literal strings from groff's Unicode transform.

If the F register is >0, we'll generate index entries on stderr for
titles (.TH), headers (.SH), subsections (.SS), items (.Ip), and index
entries marked with X<> in POD. Of course, you'll have to process the
output yourself in some meaningful fashion.

Avoid warning from groff about undefined register 'F'.

Title "d2i_PKCS8PrivateKey_bio 3" For nroff, turn off justification. Always turn off hyphenation; it makes
way too many mistakes in technical documents.
d2i_PKCS8PrivateKey_bio, d2i_PKCS8PrivateKey_fp, i2d_PKCS8PrivateKey_bio, i2d_PKCS8PrivateKey_fp, i2d_PKCS8PrivateKey_nid_bio, i2d_PKCS8PrivateKey_nid_fp - PKCS#8 format private key functions Header "SYNOPSIS" .Vb 1 #include <openssl/pem.h> \& EVP_PKEY *d2i_PKCS8PrivateKey_bio(BIO *bp, EVP_PKEY **x, pem_password_cb *cb, void *u); EVP_PKEY *d2i_PKCS8PrivateKey_fp(FILE *fp, EVP_PKEY **x, pem_password_cb *cb, void *u); \& int i2d_PKCS8PrivateKey_bio(BIO *bp, const EVP_PKEY *x, const EVP_CIPHER *enc, char *kstr, int klen, pem_password_cb *cb, void *u); \& int i2d_PKCS8PrivateKey_fp(FILE *fp, const EVP_PKEY *x, const EVP_CIPHER *enc, char *kstr, int klen, pem_password_cb *cb, void *u); \& int i2d_PKCS8PrivateKey_nid_bio(BIO *bp, const EVP_PKEY *x, int nid, char *kstr, int klen, pem_password_cb *cb, void *u); \& int i2d_PKCS8PrivateKey_nid_fp(FILE *fp, const EVP_PKEY *x, int nid, char *kstr, int klen, pem_password_cb *cb, void *u); .Ve Header "DESCRIPTION" The PKCS#8 functions encode and decode private keys in PKCS#8 format using both PKCS#5 v1.5 and PKCS#5 v2.0 password based encryption algorithms.

Other than the use of DER as opposed to PEM these functions are identical to the corresponding PEM function as described in PEM_read_PrivateKey\|(3).

Header "NOTES" These functions are currently the only way to store encrypted private keys using DER format.

Currently all the functions use BIOs or FILE pointers, there are no functions which work directly on memory: this can be readily worked around by converting the buffers to memory BIOs, see BIO_s_mem\|(3) for details.

These functions make no assumption regarding the pass phrase received from the password callback. It will simply be treated as a byte sequence.

Header "RETURN VALUES" \fBd2i_PKCS8PrivateKey_bio() and d2i_PKCS8PrivateKey_fp() return a valid EVP_PKEY structure or NULL if an error occurred.

\fBi2d_PKCS8PrivateKey_bio(), i2d_PKCS8PrivateKey_fp(), i2d_PKCS8PrivateKey_nid_bio() and i2d_PKCS8PrivateKey_nid_fp() return 1 on success or 0 on error.
