D2I_PKCS8_PRIV_KEY_INFO(3)                  DragonFly Library Functions Manual


d2i_PKCS8_PRIV_KEY_INFO, i2d_PKCS8_PRIV_KEY_INFO, d2i_PKCS8_PRIV_KEY_INFO_bio, i2d_PKCS8_PRIV_KEY_INFO_bio, d2i_PKCS8_PRIV_KEY_INFO_fp, i2d_PKCS8_PRIV_KEY_INFO_fp - decode and encode PKCS#8 private key


#include <openssl/x509.h> PKCS8_PRIV_KEY_INFO * d2i_PKCS8_PRIV_KEY_INFO(PKCS8_PRIV_KEY_INFO **val_out, const unsigned char **der_in, long length); int i2d_PKCS8_PRIV_KEY_INFO(PKCS8_PRIV_KEY_INFO *val_in, unsigned char **der_out); PKCS8_PRIV_KEY_INFO * d2i_PKCS8_PRIV_KEY_INFO_bio(BIO *in_bio, PKCS8_PRIV_KEY_INFO **val_out); int i2d_PKCS8_PRIV_KEY_INFO_bio(BIO *out_bio, PKCS8_PRIV_KEY_INFO *val_in); PKCS8_PRIV_KEY_INFO * d2i_PKCS8_PRIV_KEY_INFO_fp(FILE *in_fp, PKCS8_PRIV_KEY_INFO **val_out); int i2d_PKCS8_PRIV_KEY_INFO_fp(BIO *out_fp, PKCS8_PRIV_KEY_INFO *val_in);


d2i_PKCS8_PRIV_KEY_INFO() and i2d_PKCS8_PRIV_KEY_INFO() decode and encode an ASN.1 PrivateKeyInfo structure defined in RFC 5208 section 5. d2i_PKCS8_PRIV_KEY_INFO_bio(), i2d_PKCS8_PRIV_KEY_INFO_bio(), d2i_PKCS8_PRIV_KEY_INFO_fp(), and i2d_PKCS8_PRIV_KEY_INFO_fp() are similar except that they decode or encode using a BIO or FILE pointer. For details about the semantics, examples, caveats, and bugs, see ASN1_item_d2i(3). These functions all use unencrypted DER format. To store private keys in encrypted form, consider d2i_PKCS8PrivateKey_bio(3) or PEM_write_PKCS8PrivateKey(3).


d2i_PKCS8_PRIV_KEY_INFO(), d2i_PKCS8_PRIV_KEY_INFO_bio(), and d2i_PKCS8_PRIV_KEY_INFO_fp() return a PKCS8_PRIV_KEY_INFO object or NULL if an error occurs. i2d_PKCS8_PRIV_KEY_INFO() returns the number of bytes successfully encoded or a negative value if an error occurs. i2d_PKCS8_PRIV_KEY_INFO_bio() and i2d_PKCS8_PRIV_KEY_INFO_fp() return 1 for success or 0 if an error occurs.

d2i_PKCS8_PRIV_KEY_INFO() and i2d_PKCS8_PRIV_KEY_INFO() first appeared in OpenSSL 0.9.3. d2i_PKCS8_PRIV_KEY_INFO_bio(), i2d_PKCS8_PRIV_KEY_INFO_bio(), d2i_PKCS8_PRIV_KEY_INFO_fp(), and i2d_PKCS8_PRIV_KEY_INFO_fp() first appeared in OpenSSL 0.9.4. All these functions have been available since OpenBSD 2.6. DragonFly 6.1-DEVELOPMENT March 21, 2018 DragonFly 6.1-DEVELOPMENT
