This function base64-decodes a given JavaScript string to obtain the secret key, whose length must not exceed INT_MAX. However, because JavaScript strings are limited to v8::String::kMaxLength chars and because base64 decoding never yields more bytes than input chars, the size of the decoded key must be strictly less than v8::String::kMaxLength bytes. Therefore, it is sufficient to statically assert that String::kMaxLength <= INT_MAX (which is always true because String::kMaxLength itself is an int). Aside from being unreachable, Coverity considers the current code "suspicious" because it indicates that buffers larger than INT_MAX might actually be allocated.

This function divides an unsigned 32-bit integer by 8, effectively right-shifting it by three bits, so the result must be less than INT_MAX. Refs: nodejs#46209
