SYNOPSIS

eddsa_pk_new(void);

void
eddsa_pk_free(eddsa_pk_t **pkp);

int
eddsa_pk_from_EVP_PKEY(eddsa_pk_t *pk, const EVP_PKEY *pkey);

int
eddsa_pk_from_ptr(eddsa_pk_t *pk, const void *ptr, size_t len);

EVP_PKEY *
eddsa_pk_to_EVP_PKEY(const eddsa_pk_t *pk);

DESCRIPTION

In libfido2, EDDSA public keys are abstracted by the eddsa_pk_t type.

The eddsa_pk_new() function returns a pointer to a newly allocated, empty eddsa_pk_t type. If memory cannot be allocated, NULL is returned.

The eddsa_pk_free() function releases the memory backing *pkp, where *pkp must have been previously allocated by eddsa_pk_new(). On return, *pkp is set to NULL. Either pkp or *pkp may be NULL, in which case eddsa_pk_free() is a NOP.

The eddsa_pk_from_EVP_PKEY() function fills pk with the contents of pkey. No references to pkey are kept.

The eddsa_pk_from_ptr() function fills pk with the contents of ptr, where ptr points to len bytes. No references to ptr are kept.

The eddsa_pk_to_EVP_PKEY() function converts pk to a newly allocated EVP_PKEY type with a reference count of 1. No internal references to the returned pointer are kept. If an error occurs, eddsa_pk_to_EVP_PKEY() returns NULL.
