* configure.ac: Added --enable-large-secmem option. * g10/options.h: Add opt.flags.large_rsa. * g10/gpg.c: Contingent on configure option: adjust secmem size, add gpg --enable-large-rsa, bound to opt.flags.large_rsa. * g10/keygen.c: Adjust max RSA size based on opt.flags.large_rsa * doc/gpg.texi: Document --enable-large-rsa. -- Some older implementations built and used RSA keys up to 16Kib, but the larger secret keys now fail when used by more recent GnuPG, due to secure memory limitations. Building with ./configure --enable-large-secmem will make gpg capable of working with those secret keys, as well as permitting the use of a new gpg option --enable-large-rsa, which let gpg generate RSA keys up to 8Kib when used with --batch --gen-key.
