I am using version 0.1.7 of the wolfssl Command Line Utility. Linked to wolfSSL version 5.7.6

Description

Hello Developer,

I have a CRL file, and its CRL number field is 1340261524025379168094198301688384645909778198. According to RFC5280, the CRL parser must be able to handle CRL numerical values up to 20 bytes, which corresponds to a maximum decimal integer of 49 digits. However, the CRL number field above is a 46-digit decimal integer. The result from parsing with wolfCLU is 1318915862. So, is this a bug?

Reproduction steps

wolfssl crl -inform der -in crl_file_serial.der -text

crl_file_serial.zip

Hi @onepeople158,

Thank you for this report. I've put up this PR wolfSSL/wolfssl#8587 to handle both of the CRL parsing issues you reported
