=pod =head1 NAME 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 =head1 SYNOPSIS #include 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, EVP_PKEY *x, const EVP_CIPHER *enc, char *kstr, int klen, pem_password_cb *cb, void *u); int i2d_PKCS8PrivateKey_fp(FILE *fp, EVP_PKEY *x, const EVP_CIPHER *enc, char *kstr, int klen, pem_password_cb *cb, void *u); int i2d_PKCS8PrivateKey_nid_bio(BIO *bp, EVP_PKEY *x, int nid, char *kstr, int klen, pem_password_cb *cb, void *u); int i2d_PKCS8PrivateKey_nid_fp(FILE *fp, EVP_PKEY *x, int nid, char *kstr, int klen, pem_password_cb *cb, void *u); =head1 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 B function as described in L. =head1 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 L for details. =head1 SEE ALSO L =head1 COPYRIGHT Copyright 2002-2016 The OpenSSL Project Authors.
