With JDK 1.7 installed, keytool always outputs by default SHA1 fingerprint, not MD5. you can get the MD5 Certificate by adding -v option. use the following code:- C:\Program Files\Java\jdk1.7.0\bin>keytool -v -list -alias androiddebugkey -keystore debug.keystore -storepass android -keypass android it will output MD5 certificate as well.
I realise this isn’t exactly what you’re asking for, but there’s no point in reinventing the wheel and writing a bash version. You can simply use the openssl command to generate the hash within your script. [me@home] echo -n “value” | openssl dgst -sha1 -hmac “key” 57443a4c052350a44638835d64fd66822f813319 Or simply: [me@home] echo -n “value” | openssl … Read more
Neither. You should use bcrypt. The hashes you mention are all optimized to be quick and easy on hardware, and so cracking them share the same qualities. If you have no other choice, at least be sure to use a long salt and re-hash multiple times. Using bcrypt in PHP 5.5+ PHP 5.5 offers new … Read more
Yes, MD5 is somewhat less CPU-intensive. On my Intel x86 (Core2 Quad Q6600, 2.4 GHz, using one core), I get this in 32-bit mode: MD5 411 SHA-1 218 SHA-256 118 SHA-512 46 and this in 64-bit mode: MD5 407 SHA-1 312 SHA-256 148 SHA-512 189 Figures are in megabytes per second, for a “long” message … Read more
Git prefixes the object with “blob “, followed by the length (as a human-readable integer), followed by a NUL character $ echo -e ‘blob 14\0Hello, World!’ | shasum 8ab686eafeb1f44702738c8b0f24f2567c36da6d Source: http://alblue.bandlem.com/2011/08/git-tip-of-week-objects.html
This is how Git calculates the SHA1 for a file (or, in Git terms, a “blob”): sha1(“blob ” + filesize + “\0″ + data) So you can easily compute it yourself without having Git installed. Note that “\0” is the NULL-byte, not a two-character string. For example, the hash of an empty file: sha1(“blob 0\0”) … Read more

243,583,606,221,817,150,598,111,409x more entropy I’d recommend using crypto.randomBytes. It’s not sha1, but for id purposes, it’s quicker, and just as “random”. var id = crypto.randomBytes(20).toString(‘hex’); //=> f26d60305dae929ef8640a75e70dd78ab809cfe9 The resulting string will be twice as long as the random bytes you generate; each byte encoded to hex is 2 characters. 20 bytes will be 40 characters of … Read more
The short answer to your question is: SHA-1 is as secure as you can get. MD5 would be fine too, even MD4; but it could make some investors nervous. For public relations, it is best to use a “better” hash function, e.g. SHA-256, even if you truncate its output to 160 or 128 bits (to … Read more
