NAMEEVP_PKEY2PKCS8, EVP_PKCS82PKEY_ex, EVP_PKCS82PKEY ​− Convert a private key to/from PKCS8

---

SYNOPSIS​ #include <openssl/x509.h> ​ ​ PKCS8_PRIV_KEY_INFO *EVP_PKEY2PKCS8(const EVP_PKEY *pkey); ​ EVP_PKEY *EVP_PKCS82PKEY(const PKCS8_PRIV_KEY_INFO *p8); ​ EVP_PKEY *EVP_PKCS82PKEY_ex(const PKCS8_PRIV_KEY_INFO *p8, OSSL_LIB_CTX *libctx, ​ const char *propq);

---

DESCRIPTION​EVP_PKEY2PKCS8() converts a private key pkey into a returned PKCS8 object. ​EVP_PKCS82PKEY_ex() converts a PKCS8 object p8 into a returned private key. It uses libctx and propq when fetching algorithms. ​EVP_PKCS82PKEY() is similiar to EVP_PKCS82PKEY_ex() but uses default values of ​NULL for the libctx and propq.

---

RETURN VALUES​EVP_PKEY2PKCS8() returns a PKCS8 object on success. ​EVP_PKCS82PKEY() and EVP_PKCS82PKEY_ex() return a private key on success. All functions return NULL if the operation fails.
