[openssl-users] base64 decode in C

I believe the SSH pubkey is binary data, not ASCII, so strlen() will not work on it if it has embedded NUL chars.
As Dave Thompson suggested, instead of strlen(), use the length returned from BIO_read.

Hi Dave and Walter,
Thanks for our reply.
I'm not doing anything different for the ssh pubkey. I'm able to decode it using the "openssl enc -base64 -d -A" command. But not using the C program.
Attaching my entire code here. After getting the base64 decoded I'm calculating the MD5 sum and printing it. This works for a regular string but not for SSH pubkey.
