NAMEPKCS8_decrypt, PKCS8_decrypt_ex, PKCS8_encrypt, PKCS8_encrypt_ex, PKCS8_set0_pbe, PKCS8_set0_pbe_ex − PKCS8 encrypt/decrypt functions
SYNOPSIS​ #include <openssl/x509.h> ​ ​ PKCS8_PRIV_KEY_INFO *PKCS8_decrypt(const X509_SIG *p8, const char *pass, ​ int passlen); ​ PKCS8_PRIV_KEY_INFO *PKCS8_decrypt_ex(const X509_SIG *p8, const char *pass, ​ int passlen, OSSL_LIB_CTX *ctx, ​ const char *propq); ​ X509_SIG *PKCS8_encrypt(int pbe_nid, const EVP_CIPHER *cipher, ​ const char *pass, int passlen, unsigned char *salt, ​ int saltlen, int iter, PKCS8_PRIV_KEY_INFO *p8); ​ X509_SIG *PKCS8_encrypt_ex(int pbe_nid, const EVP_CIPHER *cipher, ​ const char *pass, int passlen, unsigned char *salt, ​ int saltlen, int iter, PKCS8_PRIV_KEY_INFO *p8, ​ OSSL_LIB_CTX *ctx, const char *propq); ​ X509_SIG *PKCS8_set0_pbe(const char *pass, int passlen, ​ PKCS8_PRIV_KEY_INFO *p8inf, X509_ALGOR *pbe); ​ X509_SIG *PKCS8_set0_pbe_ex(const char *pass, int passlen, ​ PKCS8_PRIV_KEY_INFO *p8inf, X509_ALGOR *pbe, ​ OSSL_LIB_CTX *ctx);
DESCRIPTION​PKCS8_encrypt() and PKCS8_encrypt_ex() perform encryption of an object p8 using the password pass of length passlen, salt salt of length saltlen and iteration count iter. The resulting X509_SIG contains the encoded algorithm parameters and encrypted key. ​PKCS8_decrypt() and PKCS8_decrypt_ex() perform decryption of an X509_SIG in ​p8 using the password pass of length passlen along with algorithm parameters obtained from the p8. ​PKCS8_set0_pbe() and PKCS8_set0_pbe_ex() perform encryption of the p8inf using the password pass of length passlen and parameters pbe. Functions ending in _ex() allow for a library context ctx and property query ​propq to be used to select algorithm implementations.
RETURN VALUES​PKCS8_encrypt(), PKCS8_encrypt_ex(), PKCS8_set0_pbe() and PKCS8_set0_pbe_ex() return an encrypted key in a X509_SIG structure or NULL if an error occurs. ​PKCS8_decrypt() and PKCS8_decrypt_ex() return a PKCS8_PRIV_KEY_INFO or NULL if an error occurs.
