mbedtls_pk_load_file()

int mbedtls_pk_load_file	(	const char *	path,
		unsigned char **	buf,
		size_t *	n
	)

mbedtls_pk_parse_key()

int mbedtls_pk_parse_key	(	mbedtls_pk_context *	ctx,
		const unsigned char *	key,
		size_t	keylen,
		const unsigned char *	pwd,
		size_t	pwdlen
	)

Parse a private key in PEM or DER format.

Parameters

ctx	key to be initialized
key	input buffer
keylen	size of the buffer (including the terminating null byte for PEM data)
pwd	password for decryption (optional)
pwdlen	size of the password

Note

On entry, ctx must be empty, either freshly initialised with mbedtls_pk_init() or reset with mbedtls_pk_free(). If you need a specific key type, check the result with mbedtls_pk_can_do().

The key is also checked for correctness.

Returns

0 if successful, or a specific PK or PEM error code

mbedtls_pk_parse_keyfile()

int mbedtls_pk_parse_keyfile	(	mbedtls_pk_context *	ctx,
		const char *	path,
		const char *	password
	)

Load and parse a private key.

Parameters

ctx	key to be initialized
path	filename to read the private key from
password	password to decrypt the file (can be NULL)

Note

On entry, ctx must be empty, either freshly initialised with mbedtls_pk_init() or reset with mbedtls_pk_free(). If you need a specific key type, check the result with mbedtls_pk_can_do().

The key is also checked for correctness.

Returns

0 if successful, or a specific PK or PEM error code

mbedtls_pk_parse_public_key()

int mbedtls_pk_parse_public_key	(	mbedtls_pk_context *	ctx,
		const unsigned char *	key,
		size_t	keylen
	)

Parse a public key in PEM or DER format.

Parameters

ctx	key to be initialized
key	input buffer
keylen	size of the buffer (including the terminating null byte for PEM data)

Note

On entry, ctx must be empty, either freshly initialised with mbedtls_pk_init() or reset with mbedtls_pk_free(). If you need a specific key type, check the result with mbedtls_pk_can_do().

The key is also checked for correctness.

Load and parse a public key.

Parameters

ctx	key to be initialized
path	filename to read the public key from

Note

On entry, ctx must be empty, either freshly initialised with mbedtls_pk_init() or reset with mbedtls_pk_free(). If you need a specific key type, check the result with mbedtls_pk_can_do().

The key is also checked for correctness.

Returns

0 if successful, or a specific PK or PEM error code

	)

Parse a SubjectPublicKeyInfo DER structure.

Parameters

p	the position in the ASN.1 data
end	end of the buffer
pk	the key to fill

Returns

0 if successful, or a specific PK error code
