Description
When the
startIndexinSelectRegexRevealwas large enough,GreaterThan(bitLength)at the line 36 ofregex.circomfailed because its second argumentstartIndex + maxRevealLen - 1was larger thanbitLength=log2Ceil(maxArrayLen)bits.This bug made tests in ether-email-auth failed.
I fixed that definition of
bitLengthtobitLength=log2Ceil(maxArrayLen + maxRevealLen - 1), allowing the maximum length of the second argument.I confirmed that circuit tests in zk-email-verify and the above tests in ether-email-auth passed on my local environment after this fix.
