3226 factorization. Normally the difficulty of breaking RSA is associated with the integer factoring problem but they are
3231 $\mbox{lcm}(p - 1, q - 1)$. The public key consists of the composite $N$ and some integer $e$ such that
3235 A person who wants to encrypt with your public key simply forms an integer (the plaintext) $M$ such that
3292 This will load the bignum from \textit{in} as a big endian integer in the format PKCS \#1 specifies, raises it to either \textit{e} or \textit{d} and stores the result

4425 \subsection{ASN.1 INTEGER}
4427 To encode or decode INTEGER data types use the following functions.
4443 These will encode or decode a signed INTEGER data type using the bignum data type to store the large INTEGER. To encode smaller values without allocating
4444 a bignum to store the value, the \textit{short} INTEGER functions were made available.
4460 These will encode or decode an unsigned \textbf{unsigned long} type (only reads upto 32--bits). For values in the range $0 \dots 2^{32} - 1$ the integer
4461 and short integer functions can encode and decode each others outputs.
4919 \textit{len = -128} to the function. Upon success it will return {\bf CRYPT\_OK} and \textit{N} will contain an integer which
5268 data type you can perform integer operations with. Ideally it should be four or eight bytes since it must properly divide the size

5669 example, if the input is $25$ and $24$ is valid then it stores $24$ back in the pointed to integer. It must not round up and must return an error if the keysize
