.

:
flexiber
Implementation of the BER-TLV serialization format from ISO 7816-4:2005.
ITU-T X.690 (08/2015) defines the BER, CER and DER encoding rules for ASN.1
The exact same document is ISO/IET 8825-1, which is freely available, inconveniently packed as a single PDF in a ZIP file :)
Credits
This library is a remix of RustCrypto/utils/der
.
The core idea taken from der
is to have Encodable
require an encoded_length
method.
By calling this recursively in a first pass, allocations required in other approaches are
avoided.
