Methods and systems disclosed herein describe obfuscating plaintext cryptographic material stored in memory. A random location in an obfuscation buffer may be selected for each byte of the plaintext cryptographic material. The location of each byte of the plaintext cryptographic material may be stored in a position tracking buffer. To recover the scrambled plaintext cryptographic material, the location of each byte of the plaintext cryptographic material may be read from the position tracking buffer. Each byte of the plaintext cryptographic material may then be read from the obfuscation buffer and written to a temporary buffer. When each byte of the plaintext cryptographic material is recovered, the plaintext cryptographic material may be used to perform one or more cryptographic operations. The scrambling techniques described herein reduce the likelihood of a malicious user recovering plaintext cryptographic material while stored in memory.
