* [crypto] Expose RSA_CTX_SIZE constantMichael Brown2017-06-201-1/+1
| | | | Signed-off-by: Michael Brown <mcb30@ipxe.org>
* [crypto] Support SHA-{224,384,512} in X.509 certificatesMichael Brown2015-08-021-72/+0Star
| | | | | | | | | Add support for SHA-224, SHA-384, and SHA-512 as digest algorithms in X.509 certificates, and allow the choice of public-key, cipher, and digest algorithms to be configured at build time via config/crypto.h.

* [crypto] Generalise x509_parse_bit_string() to asn1_bit_string()Michael Brown2012-05-141-11/+4Star

* [crypto] Add an explicit "RSA signature incorrect" error messageMichael Brown2012-03-271-1/+7

* [crypto] Generalise X.509 OID-identified algorithm to asn1.cMichael Brown2012-03-221-0/+47
| | | | | | | | The concept of an OID-identified algorithm as defined in X.509 is used in some other standards (e.g. PKCS#7). Generalise this functionality and provide it as part of the ASN.1 core. Signed-off-by: Michael Brown <mcb30@ipxe.org>
* [crypto] Use linker tables for RSA digestInfo prefixesMichael Brown2012-03-201-37/+26Star
| | | | | | | Allow external code to specify RSA digestInfo prefixes for additional digest algorithms. Signed-off-by: Michael Brown <mcb30@ipxe.org>
* [rsa] Actually check the unused-bits byte in the public key bit stringMichael Brown2012-03-181-3/+4

* [crypto] Force caller to provide temporary storage for modular calculationsMichael Brown2012-03-181-1/+6
| | | | | | | | | | | | | bigint_mod_multiply() and bigint_mod_exp() require a fixed amount of temporary storage for intermediate results. (The amount of temporary storage required depends upon the size of the integers involved.) When performing calculations for 4096-bit RSA the amount of temporary storage space required will exceed 2.5kB, which is too much to allocate on the stack. Avoid this problem by forcing the caller to allocate temporary storage. Signed-off-by: Michael Brown <mcb30@ipxe.org>
* [crypto] Add native RSA algorithmMichael Brown2012-03-181-0/+600
Add an implementation of RSA that uses the iPXE big-integer support. Signed-off-by: Michael Brown <mcb30@ipxe.org>
