## Format options
|
|
|
|
|
|
|
|
|
|
Currently the only option is `force` and is used to ignore some format assertion errors. It can be used as a decode option or as a CLI `-o` option:
|
|
|
|
|
|
|
|
|
|
```
|
|
|
|
|
fq -d mp4 -o force=true file.mp4
|
|
|
|
|
fq -d raw 'mp4({force: true})' file.mp4
|
|
|
|
|
```
|
|
|
|

### asn1_ber
|
|
|
|
|
|
|
|
|
|
Can also decode CER and BER but with no extra validation. Currently does not support specifying a schema.
|
|
|
|
|
|
|
|
|
|
Supports `torepr` but without schema support it's not that useful:
|
|
|
|
|
|
|
|
|
|
```
|
|
|
|
|
fq -d asn1_ber torepr file.ber
|
|
|
|
|
```
|
|
|
|
|
|
2022-02-07 19:41:05 +03:00
|
|
|
There is also `frompem` and `topem` to help working with PEM format:
|
|
|
|
|
|
|
|
|
|
```
|
|
|
|
|
fq -d raw 'frompem | asn1_ber | d' cert.pem
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
If the schema is known and not that complicated it can be reproduced:
|
|
|
|
|
|
|
|
|
|
```
|
|
|
|
|
fq -d asn1_ber 'torepr as $r | ["version", "modulus", "private_exponent", "private_exponen", "prime1", "prime2", "exponent1", "exponent2", "coefficient"] | with_entries({key: .value, value: $r[.key]})' pkcs1.der
|
|
|
|
|
```
