Openssl rand -base64 example
WebRAND_DRBG - the deterministic random bit generator. SYNOPSIS #include DESCRIPTION. The default OpenSSL RAND method is based … WebRANDFILE is used by OpenSSL to store some amount (256 bytes) of seed data from the CSPRNG used internally across invocations. This is particularly useful on low-entropy systems (i.e., embedded devices) that make frequent SSL invocations. The file is loaded via the function RAND_load_file.Looking at the source, we see that the contents of the file …
