Third-party applications, such as the incredibly useful browser-based Bit Address , can be used to decrypt BIP0038 keys. As a best practice, the level-1 children of the master keys are always derived through the hardened derivation, to prevent compromise of the master keys.

Hierarchical Deterministic Wallets Bip0032
The parent public key, chain code, and the index number are combined and hashed with the HMAC-SHA512 algorithm to produce a 512-bit hash. The right-half 256 bits of the hash output become the chain code for the child. The left-half 256 bits of the hash and the index number are added to the parent private key to produce the child private key. In Figure 4-11, we see this illustrated with the index set to 0 to produce the 0’th child of the parent. Where k is the private key, G is the generator point, and K is the resulting public key, a point on the curve.
