SYNOPSIS
        #include <openssl/pem.h>

        DECLARE_PEM_rw(name, TYPE)

        TYPE *PEM_read_TYPE(FILE *fp, TYPE **a, pem_password_cb *cb, void *u);
        TYPE *PEM_read_bio_TYPE(BIO *bp, TYPE **a, pem_password_cb *cb, void *u);
        int PEM_write_TYPE(FILE *fp, const TYPE *a);
        int PEM_write_bio_TYPE(BIO *bp, const TYPE *a);

       The following functions have been deprecated since OpenSSL 3.0, and can
       be hidden entirely by defining OPENSSL_API_COMPAT with a suitable
       version value, see openssl_user_macros(7):

        #include <openssl/pem.h>

        int PEM_write_DHxparams(FILE *out, const DH *dh);
        int PEM_write_bio_DHxparams(BIO *out, const DH *dh);
        EC_GROUP *PEM_read_ECPKParameters(FILE *fp, EC_GROUP **x, pem_password_cb *cb, void *u);
        EC_GROUP *PEM_read_bio_ECPKParameters(BIO *bp, EC_GROUP **x, pem_password_cb *cb, void *u);
        int PEM_write_ECPKParameters(FILE *out, const EC_GROUP *x);
        int PEM_write_bio_ECPKParameters(BIO *out, const EC_GROUP *x),

        EC_KEY *PEM_read_EC_PUBKEY(FILE *fp, EC_KEY **x, pem_password_cb *cb, void *u);
        EC_KEY *PEM_read_bio_EC_PUBKEY(BIO *bp, EC_KEY **x, pem_password_cb *cb, void *u);
        int PEM_write_EC_PUBKEY(FILE *out, const EC_KEY *x);
        int PEM_write_bio_EC_PUBKEY(BIO *out, const EC_KEY *x);

        EC_KEY *PEM_read_ECPrivateKey(FILE *out, EC_KEY **x, pem_password_cb *cb, void *u);
        EC_KEY *PEM_read_bio_ECPrivateKey(BIO *out, EC_KEY **x, pem_password_cb *cb, void *u);
        int PEM_write_ECPrivateKey(FILE *out, const EC_KEY *x, const EVP_CIPHER *enc,
                                   const unsigned char *kstr, int klen,
                                   pem_password_cb *cb, void *u);
        int PEM_write_bio_ECPrivateKey(BIO *out, const EC_KEY *x, const EVP_CIPHER *enc,
                                       const unsigned char *kstr, int klen,
                                       pem_password_cb *cb, void *u);

DESCRIPTION
       All of the functions described on this page are deprecated.
       Applications should use OSSL_ENCODER_to_bio() and
       OSSL_DECODER_from_bio() instead.

       In the description below, TTYYPPEE is used as a placeholder for any of the
       OpenSSL datatypes, such as X509.  The macro DECLARE_PEM_rw expands to
       the set of declarations shown in the next four lines of the synopsis.

       These routines convert between local instances of ASN1 datatypes and
       the PEM encoding.  For more information on the templates, see
       ASN1_ITEM(3).  For more information on the lower-level routines used by
       the functions here, see PEM_read(3).

       PEM_read_TTYYPPEE() reads a PEM-encoded object of TTYYPPEE from the file fp and
       returns it.  The cb and u parameters are as described in
       pem_password_cb(3).

       PEM_read_bio_TTYYPPEE() is similar to PEM_read_TTYYPPEE() but reads from the
       BIO bp.

       PEM_write_TTYYPPEE() writes the PEM encoding of the object a to the file
       fp.

       PEM_write_bio_TTYYPPEE() similarly writes to the BIO bp.

NOTES
       These functions make no assumption regarding the pass phrase received
       from the password callback.  It will simply be treated as a byte
       sequence.

RETURN VALUES
       PEM_read_TTYYPPEE() and PEM_read_bio_TTYYPPEE() return a pointer to an
       allocated object, which should be released by calling TTYYPPEE_free(), or
       NULL on error.

       PEM_write_TTYYPPEE() and PEM_write_bio_TTYYPPEE() return 1 for success or 0 for
       failure.

       PEM_write_bio_EC_PUBKEY(), PEM_read_ECPrivateKey(),
       PEM_read_bio_ECPrivateKey(), PEM_write_ECPrivateKey() and
       PEM_write_bio_ECPrivateKey() were deprecated in OpenSSL 3.0.
