ASN1 Error codes#

These error codes are combined with other error codes for higher error granularity.e.g. X.509 and PKCS #7 error codes ASN1 is a standard to specify data structures.

#define

Out of data when parsing an ASN1 data structure.

#define

ASN1 tag was of an unexpected value.

#define

Error when trying to determine the length or invalid length.

#define

Actual length differs from expected length.

#define

Data is invalid.

#define

Memory allocation failed.

#define

mbedtls_asn1_get_sequence_of#

int mbedtls_asn1_get_sequence_of (unsigned char ** p, const unsigned char * end, mbedtls_asn1_sequence * cur, int tag)

Parses and splits an ASN.1 "SEQUENCE OF <tag>".

Parameters
N/Ap

On entry, *p points to the start of the ASN.1 element. On successful completion, *p is equal to end. On error, the value of *p is undefined.

N/Aend

End of data.

N/Acur

A mbedtls_asn1_sequence which this function fills. When this function returns, *cur is the head of a linked list. Each node in this list is allocated with mbedtls_calloc() apart from cur itself, and should therefore be freed with mbedtls_free(). The list describes the content of the sequence. The head of the list (i.e. *cur itself) describes the first element, *cur->next describes the second element, etc. For each element, buf.tag == tag, buf.len is the length of the content of the content of the element, and buf.p points to the first byte of the content (i.e. immediately past the length of the element). Note that list elements may be allocated even on error.

N/Atag

Each element of the sequence must have this tag.

Updates the pointer to immediately behind the full sequence tag.

This function allocates memory for the sequence elements. You can free the allocated memory with mbedtls_asn1_sequence_free().

Note

  • On error, this function may return a partial list in cur. You must set cur->next = NULL before calling this function! Otherwise it is impossible to distinguish a previously non-null pointer from a pointer to an object allocated by this function.

  • If the sequence is empty, this function does not modify *cur. If the sequence is valid and non-empty, this function sets cur->buf.tag to tag. This allows callers to distinguish between an empty sequence and a one-element sequence.

Returns

mbedtls_asn1_sequence_free#

void mbedtls_asn1_sequence_free (mbedtls_asn1_sequence * seq)

Free a heap-allocated linked list presentation of an ASN.1 sequence, including the first element.

Parameters
N/Aseq

The address of the first sequence component. This may be NULL, in which case this functions returns immediately.

There are two common ways to manage the memory used for the representation of a parsed ASN.1 sequence:


Definition at line 437 of file util/third_party/mbedtls/include/mbedtls/asn1.h

mbedtls_asn1_traverse_sequence_of#

int mbedtls_asn1_traverse_sequence_of (unsigned char ** p, const unsigned char * end, unsigned char tag_must_mask, unsigned char tag_must_val, unsigned char tag_may_mask, unsigned char tag_may_val, int(*)(void *ctx, int tag, unsigned char *start, size_t len) cb, void * ctx)

Traverse an ASN.1 SEQUENCE container and call a callback for each entry.

Parameters
N/Ap

The address of the pointer to the beginning of the ASN.1 SEQUENCE header. This is updated to point to the end of the ASN.1 SEQUENCE container on a successful invocation.

N/Aend

The end of the ASN.1 SEQUENCE container.

N/Atag_must_mask

A mask to be applied to the ASN.1 tags found within the SEQUENCE before comparing to tag_must_val.

N/Atag_must_val

The required value of each ASN.1 tag found in the SEQUENCE, after masking with tag_must_mask. Mismatching tags lead to an error. For example, a value of 0 for both tag_must_mask and tag_must_val means that every tag is allowed, while a value of 0xFF for tag_must_mask means that tag_must_val is the only allowed tag.

N/Atag_may_mask

A mask to be applied to the ASN.1 tags found within the SEQUENCE before comparing to tag_may_val.

N/Atag_may_val

The desired value of each ASN.1 tag found in the SEQUENCE, after masking with tag_may_mask. Mismatching tags will be silently ignored. For example, a value of 0 for tag_may_mask and tag_may_val means that any tag will be considered, while a value of 0xFF for tag_may_mask means that all tags with value different from tag_may_val will be ignored.

N/Acb

The callback to trigger for each component in the ASN.1 SEQUENCE that matches tag_may_val. The callback function is called with the following parameters:

  • ctx.

  • The tag of the current element.

  • A pointer to the start of the current element's content inside the input.

  • The length of the content of the current element. If the callback returns a non-zero value, the function stops immediately, forwarding the callback's return value.

N/Actx

The context to be passed to the callback cb.

This function checks that the input is a SEQUENCE of elements that each have a "must" tag, and calls a callback function on the elements that have a "may" tag.

For example, to validate that the input is a SEQUENCE of tag1 and call cb on each element, use

mbedtls_asn1_traverse_sequence_of(&p, end, 0xff, tag1, 0, 0, cb, ctx);

To validate that the input is a SEQUENCE of ANY and call cb on each element, use

mbedtls_asn1_traverse_sequence_of(&p, end, 0, 0, 0, 0, cb, ctx);

To validate that the input is a SEQUENCE of CHOICE {NULL, OCTET STRING} and call cb on each element that is an OCTET STRING, use

mbedtls_asn1_traverse_sequence_of(&p, end, 0xfe, 0x04, 0xff, 0x04, cb, ctx);

The callback is called on the elements with a "may" tag from left to right. If the input is not a valid SEQUENCE of elements with a "must" tag, the callback is called on the elements up to the leftmost point where the input is invalid.

Warnings

  • This function is still experimental and may change at any time.

Returns

  • 0 if successful the entire ASN.1 SEQUENCE was traversed without parsing or callback errors.

  • MBEDTLS_ERR_ASN1_LENGTH_MISMATCH if the input contains extra data after a valid SEQUENCE of elements with an accepted tag.

  • MBEDTLS_ERR_ASN1_UNEXPECTED_TAG if the input starts with an ASN.1 SEQUENCE in which an element has a tag that is not accepted.

  • An ASN.1 error code if the input does not start with a valid ASN.1 SEQUENCE.

  • A non-zero error code forwarded from the callback cb in case the latter returns a non-zero value.

MBEDTLS_OID_SIZE#

#define MBEDTLS_OID_SIZE
Value:
(x)

Returns the size of the binary string, without the trailing \0.

MBEDTLS_OID_CMP#

#define MBEDTLS_OID_CMP
Value:
((MBEDTLS_OID_SIZE(oid_str) != (oid_buf)->len) || \
memcmp((oid_str), (oid_buf)->p, (oid_buf)->len) != 0)

Compares an mbedtls_asn1_buf structure to a reference OID.

Only works for 'defined' oid_str values (MBEDTLS_OID_HMAC_SHA1), you cannot use a 'unsigned char *oid' here!
