PEM_X509_INFO_READ_BIO_EX(3ossl) OpenSSL PEM_X509_INFO_READ_BIO_EX(3ossl)

NAME PEM_X509_INFO_read_ex, PEM_X509_INFO_read, PEM_X509_INFO_read_bio_ex, PEM_X509_INFO_read_bio - read PEM-encoded data structures into one or more X509_INFO objects
SYNOPSIS #include <openssl/pem.h>
STACK_OF(X509_INFO) *PEM_X509_INFO_read_ex(FILE *fp, STACK_OF(X509_INFO) *sk, pem_password_cb *cb, void *u, OSSL_LIB_CTX *libctx, const char *propq); STACK_OF(X509_INFO) *PEM_X509_INFO_read(FILE *fp, STACK_OF(X509_INFO) *sk, pem_password_cb *cb, void *u); STACK_OF(X509_INFO) *PEM_X509_INFO_read_bio_ex(BIO *bio, STACK_OF(X509_INFO) *sk, pem_password_cb *cb, void *u, OSSL_LIB_CTX *libctx, const char *propq); STACK_OF(X509_INFO) *PEM_X509_INFO_read_bio(BIO *bp, STACK_OF(X509_INFO) *sk, pem_password_cb *cb, void *u);
DESCRIPTION PEM_X509_INFO_read_ex() loads the X509_INFO objects from a file fp.
PEM_X509_INFO_read() is similar to PEM_X509_INFO_read_ex() but uses the default (NULL) library context libctx and empty property query propq.
PEM_X509_INFO_read_bio_ex() loads the X509_INFO objects using a bio bp.
PEM_X509_INFO_read_bio() is similar to PEM_X509_INFO_read_bio_ex() but uses the default (NULL) library context libctx and empty property query propq.
Each of the loaded X509_INFO objects can contain a CRL, a certificate, and/or a private key. The elements are read sequentially, and as far as they are of different type than the elements read before, they are combined into the same X509_INFO object. The idea behind this is that if, for instance, a certificate is followed by a private key, the private key is supposed to correspond to the certificate.
If the input stack sk is NULL a new stack is allocated, else the given stack is extended.
The optional cb and u parameters can be used for providing a pass phrase needed for decrypting encrypted PEM structures (normally only private keys). See PEM_read_bio_PrivateKey(3) and passphrase-encoding(7) for details.
The library context libctx and property query propq are used for fetching algorithms from providers.
RETURN VALUES PEM_X509_INFO_read_ex(), PEM_X509_INFO_read(), PEM_X509_INFO_read_bio_ex() and PEM_X509_INFO_read_bio() return a stack of X509_INFO objects or NULL on failure.
