* Encode an ASN.1 INTEGER with NULL data to value of zero.jsing2022-08-281-2/+4
| | | | | | | | | | | When an ASN1_INTEGER is created it has NULL data until a value is set - previously, an ASN1_INTEGER in this state encoded to an ASN.1 INTEGER with a value of 0, rather than being treated as an error. While code should really set values, the historical behaviour has not required this. Found the hard way by sthen@ with acme-client. ok tb@
* Rewrite i2c_ASN1_INTEGER() using CBB/CBS.jsing2022-08-201-97/+100
| | | | | | | | | | This gives us cleaner and safer code, although it is worth noting that we now generate the encoding even when called with NULL as the output pointer (and then discard it, returning just the length). Resolves oss-fuzz #49963. ok tb@
* Cast int64_t to uint64_t before negating.jsing2022-07-131-3/+7
| | | | | | | | | Avoid undefined behaviour/integer overflow by casting an int64_t to uint64_t before negating. Fixes oss-fuzz #49043 ok tb@
* Make ASN1_{INTEGER,ENUMERATED}_get() return 0 on NULL againtb2022-07-091-1/+3
| | | | | | | | This is the documented behavior which got lost in the recent rewrite. Mismatch of documentation and reality pointed out by schwarze ok jsing
* Negate unsigned then cast to signed.jsing2022-06-281-2/+2
| | | | | | | | | Avoid undefined behaviour by negating the unsigned value, before casting to int64_t, rather than casting to int64_t then negating. Fixes oss-fuzz #48499 ok tb@
* Rewrite ASN1_INTEGER_{get,set}() using CBS/CBBjsing2022-06-251-60/+177
| | | | | | In the process, prepare to provide ASN1_INTEGER_{get,set}_{u,}int64(). ok beck@ tb@
* Simplify ASN1_INTEGER_cmp()jsing2022-06-251-16/+9
| | | | ok beck@ tb@
* Rewrite c2i_ASN1_INTEGER() using CBS.jsing2022-04-271-84/+129
| | | | | | | | This also makes validation stricter and inline with X.690 - we now reject zero length inputs (rather than treating them as zero values) and enforce minimal encoding. ok tb@
* Indent goto labels for diffability.jsing2021-12-251-7/+7
| | | | Whitespace change only.
* Consolidate code/templates for ASN.1 types.jsing2021-12-251-1/+32
| | | | | | | Where an ASN.1 type has its own file, move the ASN.1 item template and template related functions into the file. Discussed with tb@
* Move ASN1_<type>_* functions to the top, encoding/decoding to the bottom.jsing2021-12-251-143/+143
| | | | No functional change.
* Consolidate various ASN.1 code.jsing2021-12-151-1/+130
| | | | | | | | | Rather than having multiple files per type (with minimal code per file), use one file per type (a_<type>.c). No functional change. Discussed with tb@
