Raw Normal View History

Add support for building the assembly versions of Blowfish encrypt and decrypt from OpenSSL. Right now we only build the 586 version, but eventually we will be able to build the 686 version based on a CPP flag defined as a result of using `cc -mcpu=pentiumpro'. We don't build the assembly version of BF_cbc_encrypt(), as it would have to be rewritten to be PIC. Performance difference is quite noticeable. Before: Doing blowfish cbc for 3s on 8 size blocks: 2891026 blowfish cbc's in 2.97s Doing blowfish cbc for 3s on 64 size blocks: 411766 blowfish cbc's in 3.10s Doing blowfish cbc for 3s on 256 size blocks: 104721 blowfish cbc's in 3.00s Doing blowfish cbc for 3s on 1024 size blocks: 26291 blowfish cbc's in 2.98s Doing blowfish cbc for 3s on 8192 size blocks: 3290 blowfish cbc's in 3.10s type 8 bytes 64 bytes 256 bytes 1024 bytes 8192 bytes blowfish cbc 7787.28k 8755.16k 8936.19k 9034.22k 8954.05k After: Doing blowfish cbc for 3s on 8 size blocks: 4573792 blowfish cbc's in 3.10s Doing blowfish cbc for 3s on 64 size blocks: 713440 blowfish cbc's in 2.99s Doing blowfish cbc for 3s on 256 size blocks: 183125 blowfish cbc's in 3.00s Doing blowfish cbc for 3s on 1024 size blocks: 46221 blowfish cbc's in 3.00s Doing blowfish cbc for 3s on 8192 size blocks: 5787 blowfish cbc's in 3.00s type 8 bytes 64 bytes 256 bytes 1024 bytes 8192 bytes blowfish cbc 12156.26k 15270.96k 15626.67k 15776.77k 15802.37k
