But how can I use this large key for AES encryption, since the maximum we can use is 32 bytes.I checked the key it is definitely not hex encoded. I am trying to encrypt a message(using AES algorithm) using an encryption key, provided by an organisation, whose length is 64 bytes.

(Rule of thumb: If a desktop computer can break a code in less than an hour, it's not strong crypto.) You're probably looking for /r/codes. Codes, simple ciphers, ARGs, and other such "weak crypto" don't belong here.NOTE: This is NOT a cryptocurrency subreddit, see /r/cryptocurrency RULESĭon't forget to read our RULES PAGE!

Current versions of ARM (32 bit or 64 bit) have 32 and 16 bit long instructions to increase code density, so up to 128 instructions could theoretically fit in your memory unit.
#256 bits in a byte 32 bit
For example, the ARM architecture initially used only 32 bit instructions, so 256/4=64 instructions would fit into your memory unit. If you are using a RISC architecture (reduced instruction set), often instructions do have a fixed length. The shortest possible instructions on an x86 machine are just 1 Byte long, so 256 instructions would fit. If the 15 byte limit applies, the minimum number of instructions, which can be stored in a 256 Byte memory unit is ⌊256/15⌋=17 instructions. In the real world, instructions on x86 machines are limited to 15 bytes. The maximum length is theoretically unlimited. Instructions can have variable length depending on your architecture.įor example if you have an x86 architecture (16, 32 or 64 bit), instructions have a variable length. The 32 bit only tells you, that memory addresses are 32 bit long so 2 32 addresses are possible (2 32 Byte = 4GiB) and registers can store equally many bits. A 32 bit architecture does not necessarily use 32 bit long instructions.
