その他
openssl には次のアルゴリズムが対応している。
options are -c to output the digest with separating colons -d to output debug info -hex output as hex dump -binary output in binary form -sign file sign digest using private key in file -verify file verify a signature using public key in file -prverify file verify a signature using private key in file -keyform arg key file format (PEM or ENGINE) -signature file signature to verify -binary output in binary form -engine e use engine e, possibly a hardware device. -md5 to use the md5 message digest algorithm (default) -md4 to use the md4 message digest algorithm -md2 to use the md2 message digest algorithm -sha1 to use the sha1 message digest algorithm -sha to use the sha message digest algorithm -sha224 to use the sha224 message digest algorithm -sha256 to use the sha256 message digest algorithm -sha384 to use the sha384 message digest algorithm -sha512 to use the sha512 message digest algorithm -mdc2 to use the mdc2 message digest algorithm -ripemd160 to use the ripemd160 message digest algorithm
