Method for providing cryptographic key pairs

A method for generating a first cipher (C_G0—O1) containing a first private key (G0) of a first asymmetric cryptographical key pair (K0), the method comprising:

• determining to generate the first cipher (C_G0—O1) ;
• generating on a computing device a second asymmetric cryptographical key pair (K1) based upon the determining, the second asymmetric cryptographical key pair (K1) comprising a second private key (G1) and a second public key (O1);
• receiving a third private key (G2), wherein the third private key forms a third asymmetric cryptographical key pair (K2)together with a third public key (O2);
• receiving a second cipher (C_G0—O2), wherein the second cipher comprises the first private key (G0) following encryption with the third public key (O2);
• decrypting the second cipher (C_G0—O2) with the third private key (G2) to obtain the first private key (G0);
• generating the first cipher (C_G0—O1) by encrypting the first private key (G0) with the second public key (O1), wherein the generating the first cipher (C_G0—O1) comprises encrypting the first private key (G0) obtained by decrypting the second cipher (C_G0—O2)and
• storing the first cipher (C_G0—O1).
